- An original upscaled video of the Lockheed P-38 Lightning.
The Lockheed P-38 Lightning is an American single-seat, twin piston-engined fighter aircraft that was used during World War II. Developed for the United States Army Air Corps by the Lockheed Corporation, the P-38 incorporated a distinctive twin-boom design with a central nacelle containing the cockpit and armament. Along with its use as a general fighter, the P-38 was used in various aerial combat roles, including as a highly effective fighter-bomber, a night fighter, and a long-range escort fighter when equipped with drop tanks. The P-38 was also used as a bomber-pathfinder, guiding streams of medium and heavy bombers, or even other P-38s equipped with bombs, to their targets. Used in the aerial reconnaissance role, the P-38 accounted for 90 percent of the aerial film captured over Europe.
P-38 armament, concentrated in the nose of the aircraft
Lockheed formed a secretive engineering team to implement the project apart from the main factory; this approach later became known as Skunk Works.The Lockheed design team, under the direction of Hall Hibbard and Clarence "Kelly" Johnson, considered a range of twin-engined configurations, including both engines in a central fuselage with push-pull propellers.
The eventual configuration was rare in terms of contemporary production fighter aircraft design, with the Dutch Fokker G.I heavy fighter, and the later Northrop P-61 Black Widow night fighter and Swedish SAAB 21 having a similar planform. The Lockheed team chose twin booms to accommodate the tail assembly, engines, and turbosuperchargers, with a central nacelle for the pilot and armament. The XP-38 gondola mockup was designed to mount two .50-caliber (12.7 mm) M2 Browning machine guns with 200 rounds per gun (rpg), two .30-caliber (7.62 mm) Brownings with 500 rpg, and a United States Army Ordnance Department prototype T1 23 mm (.90 in) autocannon with a rotary magazine as a substitute for the nonexistent 25 mm Hotchkiss aircraft autocannon specified by Kelsey and Saville. In the prototype YP-38s, an Army Ordnance Department T9 37 mm (1.46 in) autocannon (later designated as the M4 in production) with 15 rounds replaced the 23 mm T1. The 15 rounds were in three five-round clips, an unsatisfactory arrangement according to Kelsey, and the T9/M4 did not perform reliably in flight. Further armament experiments from March to June 1941 resulted in the P-38E combat configuration of four M2 Browning machine guns, and one Hispano 20 mm (.79 in) autocannon with 150 rounds.

I love the P38 and the stories of the men who flew them.
You can make it smoother using DAIN, to create intermediate frames.
I'm not sure if it works better before or after upscaling.
Great nostalgic look of legendary aircraft
👍🙏
Had no idea it flew so well on one engine.
Imagine being 23 years old in 1942 and flying this war bird
My favorite WW II plane.
"these are lethal weapons" **shows fuzzy picture of blobs flying**
Its a shame that the digitization can’t retain the original clarity. The original film version wasn’t blurry like this.
Is there anyone on here who could calculate a P-38's performance powered by a pair of 3000 hp Napier Saber or Rolls Roycw Griffon engines set up like the standard Allison v-1710 engines. I think that modified that way it should approach 500 mph max, but lack the formulas to verify this gut feeling
At what model did they start putting a generator on each engine?
