WWII Rare Archives: Allied Proving Grounds Inside the Final Technological Push

In the closing months of World War II, military aviation engineering underwent a rapid transformation as Allied proving grounds tested radical airframes, heavy ordnance, and high-altitude propulsion systems. This 4K restored archival documentary preserves both the classified 1945 technical evaluations from Wright Field and Eglin Field and the complete transition training curriculum for the Republic P-47 Thunderbolt. The film opens on Okinawa with an intelligence inspection of a captured Japanese Yokosuka MXY-7 Ohka ("Baka") rocket-propelled suicide bomb, detailing its three-rocket propulsion system and 535 mph terminal speed. Next, the focus shifts to the long-range Republic P-47N Thunderbolt, engineered for Pacific escort missions over Japan with a 20,000-pound combat weight, squared wingtips, wet wings, and a 13-hour endurance demonstrated on a high-speed transcontinental flight from Los Angeles to Wright Field. At Hawthorne, California, cameras document the assembly of the Northrop XB-35 Flying Wing bomber, spanning 172 feet with four buried Pratt & Whitney R-4360 Wasp Major engines driving contra-rotating pusher propellers and eight bomb bays housing up to 51,000 pounds of ordnance. Technical evaluations continue with the German Rheinmetall-Borsig MK 108 30mm cannon from the Messerschmitt Me 262, Aero Medical Laboratory centrifuge tests measuring how 1.4G to 3G radial forces immobilize pilots attempting to bail out of spinning aircraft, and sub-zero arctic exposure suit trials in the frozen waters of Huffman Lake. At Wright Field, engineers test the single-tail Consolidated B-24K Liberator with a Bell power-boost nose turret alongside a rocket-propelled rescue line-throwing pistol. At Eglin Field, a modified Boeing B-29 Superfortress conducts high-altitude drop trials of the 12,000-pound British "Tallboy" earthquake bomb, followed by Range 64 launch trials of the JB-2 pulse-jet missile using rocket carts, 17G multiple-cartridge powder tubes, and high-pressure steam catapults. The second half presents the complete USAAF P-47D Thunderbolt flight instruction program at Pine Castle Army Airfield: Pratt & Whitney R-2800 Twin Wasp mechanics, General Electric turbosupercharger cutaways, water injection war emergency power, clockwise cockpit checks, taxiing, ground-loop prevention, stall recovery, critical-altitude turbo management, 500 mph dive compressibility charts, and combat aerobatics including the loop, slow roll, Immelmann, spin recovery, and power-off Split-S.
