You explained nothing about the stubs and said the wings fold?

A modern marvel, built in retro times. I'm not even close to flying, but if I was and I could build a plane, this would be my first.

This design desperately needs a re-visit with modern technology and manufacturing taken into account

They only manufactured 5 aircraft. Adams already started working on a jet prototype before the 500 had even started to sell. They owed Centennial airport $850,000.

Why are my comments being removed? Maybe cause it was a URL of the fight club faces

Would this have a low radar profile?

I like that to show it's range they show taking off in Wichita KS. The Air Capitol of the World.

i can do all the things required but damm i wouldnt attempt it

Looks very unstable.

That's a young me, at 10:00 mark, giving my U-control JD-2 model to John at Rockford in 1967.

Fascinating! Just to point out to younger viewers, John must have visited West Germany in the cold war era because there was no re-united Germany back then (see also the map in the video). Sorry about nit-picking.

Extremely intelligent work!

Absolutely interesting and also fascinating to know, that this aircraft inventor sold blue-print of the aircraft and challenged people who would be interested to build their own plane. Hope one day, I can get the blueprint and make it for myself, in India. 👌👌👌❤️❤️❤️😊😊😊

It's genius aa it is shocking it never became a production aircraft with that kind of speed and cost to fly. No doubt like many aircraft the manufacturer would price it out of most budgets sadly.

Was that an UFO @ 07:12 ??

Very very cool aircraft

Ok, so where can I get the plans from?

Very interesting. The video does not explain the relevance of the vertical prong to the fact that the wings can fold. Second point: why not sell this as a kit, eg with the welding already done? There may be a good reason, but let's see it spelled out.

Good story. Some of the stock footage made this almost unwatchable

I was thinking the same thing

Looks like me on my first solo…😂

So you're telling me that plane was able to get the same MPG as fullsize truck? That's pretty awesome.

Awesome !!!

So, what are the stubs for? You inferred they are used in folding the wings but never directly said so nor showed them in use. I don't see them on the yellow model.

The biggest drawback to this plane probably is the high speed, a slow plane is easier to fly and navigate.

You know an aircraft is perfect when the only way to get it is to build it yourself.

when laser welding of 3130 steel is FAA approved together with computer "notching" of tubes , there may be a future for more such designs.

What's the closest thing to the Delta today?

5:10 the shadow look like a d..stick.

Wow he built a tiny delta wing plane with a 180hp engine from scratch. Absolutely amazing.

So why did that design never become the standard for small, recreational aircraft?

Nice job, AI. Always easy to tell with it's bad pronunciation. A lot of the text is straight from the Wiki page. Well, maybe the voice is an American gen Z dumbed-down dude that can't speak English.

Has the LGBT Community given us the "okay" to say this word? 🤔

With all of the composites that we have now, what is the real drawback to being able to create a kit plane? I also wonder about building a larger version keeping everything to the same scale? With fuel injection, turbocharging and the like, why couldn’t this be done?

The ending tag line makes me want to see it doing stall recovery from a high-alpha maneuver. Am I odd for saying that?

Incredible!

Has everyone forgotten the Wright Brothers? They didn't have computers or car or even another engineered design to crib from. They had to work from nature.

I'm not sure "groundbreaking" is how I'd want the design of my aircraft to be described. Breaking the ground is something I try avoid every time I take off.

If it's an efficient design, wouldn't it be a good candidate for electrification? Throw in some modern composite materials and other improvements and you would have quite an impressive machine even by modern standards?

dang, that thing just wants to leap off the ground. it makes me sad that my country has fallen from grace and no longer has the competency to build aircraft like this.

That delta plane would make an affordable high explosive military drone

I think having one decided out for sporting trips that is just something I find cool about it

Good story

beautiful! lovely! want one!

This was great to watch. What a well thought out design! Last summer I was in Oshkosh for work and heard an airplane fly over and from below it looked like a fighter jet but it flew too slow and sounded like a piston engine. I'd wondered about that plane ever since. Now I know what it was and I am impressed.

Spectacular design; considering it was nearly 50 years ahead of it's time! Love these planes, and yes, John was right...they DO fly the way an airplane should fly; just ask the F-22 pilots today! :)

those stark biplanes look as if he read some very old data i recently dound by chance from Naca tests on biplane configurations...some claimed the least drag was possible at 30% Gap on 1 cord stagger...and his by eye balling looks like that concoction, but actually those were just drag tests and no lift tests...wonder how fast it needed to go bcs interference must be enourmous!

Got to see one of these fly over my house the other day, turns out there is an owner at my local airport.
