I fly fairly often, and I think more and more pilots are watching Kelsey's videos. They've upped their game with the PA's. I haven't heard the "aaa" in a couple of years. Congratulations, Kelsey! Your videos not only entertain the general public, they're also instructional videos for the pilots!

@@ajs11201 I, unfortunately, was able to fly somewhere for the last time in 2017 so super long time ago, and both pilots from Qatar Airways (Narita➡️Doha➡️Warsaw) were making a lot of "aaaa" 😅 I'm wondering if something now has changed.

@J Hemphill a lot of Qatar Air pilots are from the UK. So, not so much of a foreign language. Arabic being the spoken language in Qatar, but English is also very common, as they used to be a British protectorate.

@@ajs11201 I was thinking the same thing recently! No "aaaa"s from the pilots 🙂 And the last couple of PA's I've heard were so put together they were like read by an actor 😃

Foreal 💯

He's so passionate and enthusiastic and obviously enjoys it

Legend has it he piloted the rest of that flight, and never left the cockpit

I heard of a child who was allowed to sit in the copilot's seat. He was told he could hold the controls. Then the captain relaxed back with his hands behind his head. The boy's knuckles turned white as he told the captain, "But I don't know how to fly." Not realising the autopilot was engaged!

No one is born to be anything my friend. It takes hard work to get to that stage, you don't simply just come out of your momma and 'wow hes going to be a pilot!' or doctor, etc. Me and my sister actually did exactly what he mentioned back in the 90s. On a flight from South America we were let into the cockpit. Did I become a pilot? Nope, but guess what? I still love planes just as much, as I just chose to go and learn to become a good surgeon and I save lives for a living.

Whats the story about vertical operation between a concorde and SR-71 over the ocean? Dont think Ive heard it

@@antisoda Little pay out but was still good, thanks

@@awhahoo the story comes from former Air Traffic Controller Peter Clarke. He wrote the following: Flying between 55,000 to 60,000ft Concorde was above the subsonic jet aircraft. It was given this vertical profile of 5,000ft as the actual altitude the Concorde would level off at depended on the actual temperature on the day. This temperature could also vary during the crossing so the aircraft would adjust altitude accordingly. One or 2 executive jet aircraft could possibly reach 43,000ft on a good day but they were still not a problem to Concorde. On one particular day, however, I did control another aircraft that could more than match Concorde both in speed and altitude, the American military SR-71 Blackbird Mach 3+ spy plane. Sometimes military aircraft crossing the Atlantic would have a reserved route kept clear for them in order for formations of jets to refuel en-route, as necessary, from an accompanying tanker. The SR-71 had more than sufficient range for the crossing and was operating solo. Although we would control many American subsonic aircraft like the C-141 or C-17 heavy cargo aircraft or maybe even troop carriers on our Track system they would not communicate with our HF radio station near Shannon. Instead they would use an American military HF radio station (Croughton) in Oxfordshire. Like most military units they had a regular change of staff so, generally, the radio operators had very limited experience of the operations they were handling. Keep it simple for them and it was OK. Anything out of the ordinary and it caused much confusion. I was controlling a westbound Concorde just entering my airspace when I received details of an SR-71 coming eastbound on a route that would conflict with Concorde. The SR-71 did not always fly supersonically, it was doing less than Mach 1 on this day, but it was still at a very high altitude. I had been told it was “above 600”, i.e. above 60,000ft. Concorde was operating up to 60,000ft and the vertical separation standard at that altitude was 4,000ft. I sent a message to the American radio operator to ask for the exact altitude of the SR-71. A few minutes later the answer came back, “Above 600.” I telephoned the radio operator explaining I needed the exact altitude. The radio operator’s response was, “I’ll patch you through.” The operator had a facility to operate a 2-way switch on the radio. Push it one way and you could transmit over the telephone, switch it the other way to receive. At the end of each transmission you had to remember to say “Over’ in order for the radio operator to know when to flick the switch. I was now talking directly to the pilot of the SR-71. “This is the Shanwick controller, confirm your altitude. Over.” SR-71, “We are above 600. Over” Me, “I need to know your exact altitude. Over” SR-71, “Above 600. Over”. Me, “Am I to understand you are unable to give me your exact altitude? Over” SR-71, “Affirmative. Over” (These aircraft had a stealth capability and could fly at very, very high altitude, often above 70,000ft. They did not, however want anyone to know exactly at what altitude they were flying so would switch off their radio signal that would indicate altitude to a radar operator once they climbed.) Me, “OK, I have a Concorde operating westbound on a conflicting route with you at 60,000ft. I need 4,000ft vertical separation. Do I have it? Over” SR-71, “You sure have.” Me, “That’s all I need to know. Thanks. Out”

Descending to 60000 ft?!? Man 😂

Sounds like Brian Schul and Walt Watson

Did the pilot ask you if you liked gladiator movies?

1967, DEN/Stapleton, Frontier Airlines. It was a different time, sweet memories.

I remember my first flight, that was so long ago, it was right after they invented air. Yeah, I'm old enough to have participated in the Great Earth Dirt Delivery Project, so I am indeed older than dirt. ;)

🤣🤣 to both of you!

Now Pontius teaches Pilates. “I wash my hands of your stiff, flabby body.”

Did you ask if the plane can fly supersonic? Because the answer is the same: once.

You always want to be in the front. In case the plane snaps in half then at least you are with the pilots.

I haven't flown for several years, so I haven't had the wonderful experience of passenger temper tantrums. But years ago we had a fun medical emergency while flying from SeaTac to LAX on a Sunday morning. As we approached L.A., the captain informed us there was a lot of traffic and we'd have to wait to land. Meanwhile, a guy in the seat behind us had partied too much the previous night and was feeling it. The flight attendants brought him an oxygen bottle. The pilot declared a medical emergency, dropped the right wing so that we turned just short of downtown L.A., then headed straight in. No holding patterns for us that day! We had an exciting ride, and the ailing passenger turned out OK.

Welcome to the Age of Paranoia. 😢

Those who give up freedom for security deserve neither. Maybe one day politics will not be ruled by panic and emotion, but a measured proportional response to threat. Nobody asked for it. Most people hate it. If it varied from airline to airline people could vote with their feet. But no. You must be insulated from all risks. I do appreciate they took smoking off, but i would appreciate better air quality. The truth is the radiation exposure from air travel probably kills more people than the hijackings and terror did at its height. Good luck finding protection there.

Airlines *could* provide their own security, and it would be a lot better - they have a billion dollars worth of investment to protect, after all. But why bother, when you can get the taxpayer to pay for your "security?"

Airport security is like the gun control debate. While I understand the need for security and vigilance, those terrorists were just bad actors. But because someone took advantage of the system, copycat criminals will try to do the same. It's a matter of balancing the extra security, and ensuring our technology is up-to-date.

It can still happen on the ground. A few years ago when we were boarding in Baltimore, the pilot saw us coming and and asked if our son would like to checkout the cockpit. He was in there through the whole boarding process and they let him make the preflight announcements.

when i was about 4, in 2004/5 there was a delay and the pilot let some parents with kids come and see the cockpit, when i got there my dad asked how long have they been pilots and one of them said it was their first ever commercial flight, my mum wasnt a fan of flying so we kept that a secret from her aha

@@robbiegillibrand3892 Maybe they were joking about their first flight. If I was a pilot I would tell people I have never flown before just to freak them out. That's probably why they don't let me be a pilot. :)

@luxplanes sup

Good man...I was waiting for someone to point out his mistake. I'm flying 25 years now and I only found out that small niche of trivia, even though I've actually worked on 733's & 34's with them. Very few pilots actually know that info.

I second that wholeheartedly! I was a USAF navigator on C-141s and C-5s decades ago. Those aircraft were built with ports and mounts in the cockpit ceilings for extension of periscopic sextants. Of course we used them for celestial navigation (GPS and INS weren’t available), but there was a nifty housekeeping use for the ports too. We could mount a long hose to the port and use the external rushing air to vacuum the cockpit.

These ports are Astrodomes right? Or similar? I’ve seen on some British Second World War bombers that they’re situated often behind the main glass of the cockpit, within easy reach of the navigator’s position (A navigator often having an area he can black out with a curtain and attend charts and maps with a lamp)

@@eagleclaw899 The only similarity to astrodomes is that the ports and the mounts are fixtures in the cockpit ceiling. The sextant used is not handheld. It is attached to the ceiling via the mount and has a barrel that extends through the port so that the navigator can periscopically observe the heavens via special optics. A blackout curtain is not necessary.

I agree with Ernst. The eyebrows are not for navigation.

Unfortunately... Some people do take offense for jokes this day. I also think his airlines not going to appreciate that. :)

I find the videos both entertaining and informative, as I had no interest in aviation until recently when I saw a livestream of planes coming in to land during the brutal crosswinds duration storm Eunice at Heathrow by BigJet tv. Not only were the pilots really having trouble keeping the planes level enough for landing-and having an astonishing number of go arounds, but they were flying diagonally. I had no idea planes could even do that, let alone deliberately. So I did a couple searches on KZfaq, read a few basic concepts regarding how aircraft actually fly and promptly tumbled down the rabbit hole. 😁 The irony is that I don’t actually like flying because it both makes me nervous and has some odd moments of a feeling very much like vertigo at certain times during flights.

They probably didn't have enough time and enough movie props to feature a greater variety of cockpits...

Yeah, they're not for sextant use, but I've heard that said before. One of those urban legends that catch on. The 707 (from which the 727, 737 got their cockpit/fuselage design) was originally designed to be a military aircraft, and my guess is that the military wanted panoramic views.

@@SteichenFamily Good answer!

Eyebrow windows were not used for sextants, they were to give the pilot a view of the runway when turning onto final. Only needed when the captain was turning right onto final, or the FO turning left onto final. It was eventually realized that they were not really all that helpful so they don't install them anymore, which saves a bit of money.

@@StevePemberton2 They were also helpful during in-flight refueling.

I'm not a pilot but I also think thinner air means less oxygen going into the engines and less oxygen means less power for engines. Just like cars have less power in higher altitudes. So thinner air less lift from wings and less power from engines. Correct me if I'm wrong of course. =)

They probably were now revering to the weather spots on the weather radar as potholes from then on. It is a decent analogy. Hitting them is bumpy, avoiding them is smoother.

@@mandowarrior123 Yes!

Oh my gosh, while I certainly wouldn’t begrudge a flight attendant needing to sit on my lap during rough turbulence and indeed if it happened when they were close enough to me and lost their balance I’d probably try to grab their arm to try to give them enough time to grab seats or regain their balance… but sitting down next to me and asking to hold my hand because she’s afraid of the turbulence? 😱 I’m a nervous passenger at the best of times and during the few times that I have flown, I’ve looked to the cabin crew to gauge if the flight is normal and safe or not by how they are reacting! If that happened to me we’d probably both end up curled up in the foetal position, rocking back and fourth constantly muttering that we’re going to crash and burn. 😆 But seriously though I’d probably agree and we could swap stories about why flying can be unnerving.

Honestly it makes no sense that LORAN would stop being a thing, since GPS could go down fairly easily

Also when the old guy repeated the statement "I'm glad you went to bat for me" it was a poorly delivered reference to hypoxia which is possible at those altitudes if you don't have oxygen and pressurization fails. Because your brain is starving and is not functioning. There's a channel called Smarter Every Day that covers the topic. It's pretty neat stuff.

@@Colt1775 no, he is senile, he has dementia.

@@Colt1775 I took it to be dementia. But I've had very recent experience with an old lady who could not remember what she just said to me 5 minutes previously. She would say the exact same thing again, or ask the exact same question.

That isn't strictly true. It cannot maintain level flight. This aircraft pitched up and climbed, inevitably the aircraft would fall again, but the speed from lower altitudes can be preserved. It isn't safe in any way, and may well damage/destroy the aircraft but that isn't to say,it isn't possible. Its just a case of trading speed for altitude. I think its safe to say nobody has tried it in a 747 to know the answer to what altitude is possible. A 747 does have a lot of drag, so it would likely depend when the engines flamed out- which would also depend on which engines it had. Its capable of over 800 feet per second and is extremely light due to the short trip. It would have to start lower than service ceiling to get a good angle of attack, but you could convert a good portion of that energy into vertical speed and thus altitude. This is known as a zoom climb. Max certified on a 747 is 45,000, (sp, short version for more range) one important thing to note is that it is limited to that due to fuel tank icing issues i believe, not on power.- there are anecdotal reports of it doing 50-55,000 but that wouldn't be legal of course. So fl 600 is plausible on a 747sp in a zoom climb.

Search the phrase "Coffin corner" to find a good description of why planes can only go so high.

They mostly certainly can. But the question is how long they can stay there before something gets damaged or they go full stall.

Sometimes turbulence can actually drag you upwards. I've heard of gliders getting caught in updrafts and gaining thousands of feet in the time it takes them to escape, and one instance of a super glider designed to try to set some fun altitude world records doing exactly that. I am curious what Kelsey has done in reverse, with random altitude gains he had to dive out of. Admittedly a powered plane has more tools to avoid rising air.

@@glenmcgillivray4707 mountain waves are extremely fun in gliders. But I haven't heard of anyone ever being unable to come back down. I have heard of pilots losing track of their altitude and getting hypoxic. Waves and thermals aren't turbulence though. They just tend to cause turbulence in certain areas.

​@@ascherlafayette8572 The Mojave desert is a great place for glider's. The updraft from the Tehachapi Mountains can lift you so fast. My first glider ride was at an airshow at the California City Airport. They we're selling glider ride's. When I was young, I would walk around the hangers looking for someone who was getting ready to fly and ask if I could go flying with them. No, I don't know these people. Yes, I'm a kid, around 10 years old walking around asking stranger's to go flying. Times were simpler when I was a kid.

I'm interested in an answer too. Back in the 70's my mom and I were on a small commercial plane going from Arkansas to Dallas/Fort Worth. Our plane hit turbulence and dropped. I had a cup ofcoke in my hand. As I and the cup dropped, felt like we fell out of the sky to young me, the coke remained at the same elevation until it hit the ceiling of the plane and then dropped all over me. To this day, not having a lid on my drink while flying is anxiety producing.

in my little Single engine airplane, i flew on a nice very sunny day to a iceland, spend the day there. on our way back it became bad in the sky with hidden thunder clouds. I missed the latsest onroute metar's, only my destination and departure. halfway i had a super fast drop from 9000 till 7000ish in my feeling in less then 45 seconds. Super scarry due to it all beeing so fast and your reaction is to pitch the nose up. while the only real solution is to get asap out of it. Now i dont know, does it also happen with bigger planes in such a aggressive way?

It’s a MOVIE!

If you’re looking for a scenario that could lead to an older first officer and younger captain, one example is pilots who do a stint in the Air Force first. A 10year contract in the AF will put a serious dent in a pilot’s seniority when they switch to commercial. And with the way the airlines are actively recruiting young people it could get even more significant. My daughter is being recruited by airlines before she has even officially started college to skip the AF and enter their direct to the airlines program at her university. The program has been around for a while, but with the pilot shortage they are recruiting young people like crazy. It’s interesting to think about the difference in seniority she could have at Delta or United vs if she flew in the Af for 10 or 20 years.

I still have my ValuJet wings I got as a kid.

@@samiam619 It's a MOViE??? REALLLLY??? Wow, I sooooo did not know that! Thank you so much for clarifying that it was a movie because I would have never known if not for you.

A flight engineer and a navigator! That cockpit was full lol. Great film, all star cast. Another good one for review Zero Hour with Dana Andrews. An ex-WWII fighter pilot with PTSD who has to fly when the crew gets food poisoning.

Yeah I have had that happen. The worst are downdrafts. I don't mind shaking but I will never get uses to sudden loss of altitude

Wake turbulence is interesting. It hangs around for a while - usually it descends from where it was produced, but it can be slow to do so. In a small plane, I've crossed my own wake turbulence when doing a 360 degree (2 minute) turn. Just a little bump, but neat to experience. (Whole different story when it's a large, heavy aircraft making the turbulence!)

There is less air resistance at higher altitude, so the concord few at high altitude to reduce the power needed at lower altitudes. Same as why the SR-71 flew at over 60,000 feet.

I read the quote as “Though I fly through the Shadow of the Valley of Death, I shall fear no Evil. For I am at 90,000 and climbing” SR71 motto

This was a zoom climb, not a sustainable action

@@robertheinkel6225 The SR-71 also flew that high because it was above the range of Soviet missiles and fighters.

Interestingly enough, if the engines do flame out and the airplane is high enough then it’s possible for them to glide. Most commercial planes have a little propeller that can be deployed that uses the air rushing by due to the speed to power some of the electronics and flight controls. From what I understand it gives the pilots just enough control to manage the glide. Obviously the plane is still descending and has no power to lift and regain any height but the glide can be long enough for the pilots to either reach an airport if one is close enough and even land on a runway safely, or to at least try to pick a place to set down without killing everyone aboard. The most obvious example of this is “the miracle on the Hudson” where a birdstrike took out both engines and yet the skilled and lucky pilot was able to glide his plane and ditch it into the river Hudson without killing anyone. I think the whole “glide it onto a runway” thing has happened at least twice. Another possibility the pilots might have is to get the engines restarted using the same basic principle as the little emergency propeller. Go fast and hope the wind is enough to get the fan blades turning fast enough to aid a restart. Obviously they have to be undamaged for that to actually work. But of course if the plane just isn’t high enough to even get a glide, or at least not one long enough to do anything such as very soon after takeoff then yes the plane is doomed and sadly that has also happened on more than one once too.

@@mikoto7693 of course it is possible to restart the engines in the air if they are not damaged and there is fuel. Yes, I know sometimes that isn't the case, like the Gimli glider (no fuel) or the miracle on the Hudson (severe damage to both engines)

There was a crash caused when the pilots went too high, the engines flamed out and shock-cooled, and the engines seized. I think Mentour Pilot covered it.

60,000 feet is one place where s commercial jet could be both stalled and over speed. Stall and over speed get closer together the higher the plane flies. At some point they get too close together and that is the ceiling of the aircraft (ok, add weight calculations to adjust this).

@@johnmcleodvii or otherwise known as coffins corner

I didn’t know that, but after thinking about it for a few moments I realised that kinda makes sense in a cold sort of way. There’s nothing the passengers can do to change the outcome either way. The pilots are trained to descend to a height where breathing is possible as quickly as possible so 10 minutes is still pretty generous. Never experienced it myself but apparently to a passenger it would seem like the plane was falling from the sky. Given the nature of gravity, usually when an aircraft suffers a catastrophic failure, descending is usually the least of pilots worries. As the saying goes, it’s not the fall that kills you, it’s the landing.

Yeah, and the passenger oxygen masks aren't actually connected to oxygen bottles/tanks like the pilot ones. Passenger O2 masks are all fed by a single-use chemical reaction that produces oxygen for about 10 mins after it's triggered. Purely a stopgap to keep passengers conscious for a few minutes while the pilots get the plane back down below 10,000 feet.

@@mikoto7693 yep, it's called an emergency descent. Autopilot setup, engines at idle, spoilers out and down she goes. Fast. Probably scary as hell for some passengers but necessary to keep them alive.

The oxygen is supplied from a little canister that is like a grenade. It has a firing pin that is popped when you pull the tubing, and it ignites a combustion process that releases oxygen. Really fun (by which I mean: not fun) when you're working on a panel, and accidentally set one off. There are pins you can insert into the firing pin to prevent this, but they aren't perfect, and neither are the people who work on them! There''s a special container for disposing of used or expired canisters - you never want to put one into the container for flammable waste products! (That would be what we call a "bomb.")

Yeah Concord and Concorde typically flew at 59,000 feet, The one I flew in definitely did.

As the Concorde burned fuel, it would become lighter obviously and climb to 60-61k feet.

@@appleiphone69 FL600 is the end of controlled airspace. Everything above it is not ATC controlled. I never heard of a Concorde flight that went above FL600. Can you provide an example, with date and flight number?

@@RustyITNerd I know the test pilots had her above but I am not aware of her doing it with passengers.

@@RustyITNerd in the early days it definitely flew higher as they used to fly a cruise climb profile.

That´d be 9 minutes at a 6,700ft/m vertical, then 9 minutes at the negative... "impressive" is not quite the word...
