\"Cutting edge for WWII. Shows a segmented shatterproof airborne oxygen tank that doesn't explode when shot by bullet rounds. Next segmetn shows the JB-2 which the US borrowed from the German design to create their own \"\"V-1 Buss Bomb.\"\" The JB-2, built by Republic Aviation (airframe) and Ford Motor Company (pulsejet engine), was reverse-engineered by inspecting V-1 wreckage found in England and was first flight-tested less than four months after the first V-1 attack. While the first flights were from Eglin AAF, Florida, extensive testing was also done at Wendover Army Air Field in Utah, launching only a few hundred feet from the sheds where delivery methods for the first atomic bombs were being developed under Project Alberta. The JB-2 was intended as a weapon in the planned invasion of Japan, but Japan surrendered and the invasion did not take place. Following the war, testing at Wendover continued, including comparison tests between the original German missile and the American copy. Later, preliminary design work was done on a small atomic warhead to be fitted to the JB-2, but it was never built.\","\"Cutting edge for WWII.
