This United States Navy pilot training film titled “Fly High and Live - Oxygen Equipment” is from 1944. The film explains the oxygen equipment used by pilots when flying at high altitudes. It demonstrates the functions and correct use of the diluter demand regulator, the oxygen cylinder tank, and the type 14-A oxygen mask worn by the pilots.
Credits (00:06). “Fly High and Live - Oxygen Equipment” title banner (00:12). War ships and planes (00:21). A Vought F4U Corsair American fighter aircraft lands (00:26). The pilot exits (00:41). He wears a type 14-A oxygen mask (00:49). Its diluter demand regulator and the oxygen cylinder (00:58). Vought F4U Corsair (01:04). The demand feature on the diluter demand regulator is explained (01:01). Vought F4U Corsair (01:27). The diluter feature on the diluter demand regulator is explained (01:34). Grumman F6F Hellcat American fighter aircraft (01:48). The pilot wears a type 14-A oxygen mask (01:52) and the aircraft is equipped with the diluter demand regulator (01:56). Graphics and photos of older and newer regulator models explain the functions of the diluter demand regulator (02:12). The functions of the regulator when at sea level vs. high altitude is explained (04:25). Graphics explain three additional features in the regulator: the check valve, pressure reducer, and emergency valve (06:47). The use of the emergency valve is demonstrated (07:36). The correct and incorrect use of the diluter feature is demonstrated on a regulator (07:56). Graphics explain the diluter feature’s correct and incorrect use as planes reach higher altitudes (08:15). It demonstrates how long a pilot will have oxygen when using the diluter correctly (08:57). A Grumman F6F Hellcat aircraft prepared for take-off from an aircraft carrier ship (09:27). A pilot enters the aircraft (09:40). He inspects the oxygen equipment, firstly checking that the emergency valve is closed (09:54). He then opens the oxygen (10:07). He ensures the pressure is equalized (10:16). He closes the oxygen to test the cylinder for leaking (10:27). He tests his mask (10:42). He reopens the oxygen cylinder (11:08). A mechanic approaches the aircraft to check the oxygen leakage (12:04). The cylinder and regulator is checked again for leakage (12:28). The mechanic walks away from the plane (12:47). The pilot secures his type 14-A oxygen mask (12:50). He tests the diaphragm (13:18). He tests the emergency valve (14:04). Many Grumman F6F Hellcat aircraft prepare for take-off (14:49). They take-off one by one from an aircraft carrier ship (15:07). Views of one Grumman F6F Hellcat aircraft flying (15:45). The altimeter in the aircraft (15:56). The pilot opens the oxygen (16:02). He removes his gloves and puts on the oxygen mask (16:12). The regulator and oxygen flow indicator are checked (16:33). Flying Grumman F6F Hellcat aircraft (16:45). Aircraft start firing (16:54). An aircraft crashes into the ocean (17:02). Flying Grumman F6F Hellcat aircraft (17:05). A pilot is suffering from oxygen loss due to his mask leaking (17:15). He opens the emergency valve (18:06) and lowers his altitude to below 10,000 feet (18:24). A pilot suffers from a headache due to carbon monoxide gas entering his cockpit (18:36). He opens the oxygen, turns off the regulator and wears his oxygen mask (18:51). Pilots use their oxygen mask and the regulator while flying in darkness due to impairment of vision (19:15). Planes land on an aircraft carrier ship (20:00). A Grumman TBF Avenger American World War II-era torpedo bomber (20:08). A Curtiss SB2C Helldiver carrier-based dive bomber (20:16). A Douglas C-47 Skytrain or Dakota (RAF designation) military transport aircraft (20:21). A North American B-25 Mitchell is an American medium bomber (20:26). Possibly a Consolidated Model 28, more commonly known as the PBY Catalina flying boat (20:28). An aviation equipment and survival officer provides instructions (20:48), supervises installation and services of oxygen equipment (20:59), and teaches pilots about the oxygen equipment (21:05). “The End” text overlay (25:40).
Motion picture films don't last forever; many have already been lost or destroyed. For almost two decades, we've worked to collect, scan and preserve the world as it was captured on 35mm, 16mm and 8mm movies -- including home movies, industrial films, and other non-fiction. If you have endangered films you'd like to have scanned, or wish to donate celluloid to Periscope Film so that we can share them with the world, we'd love to hear from you.
