B-52
TWA was working on a “Super Constellation”. Boeing produced the six-engine B-47 bomber for the U.S. Army. Hughes himself accomplished his successful test flight of his Hercules airplane, known as the ‘Spruce Goose’, still the largest plane ever built, at Long Beach, California, on November 2, 1947. Boeing designed an eight turbojet engine B-52 bomber in 1948. Also in 1948 the standardized air refueling, in this instance between two B-29s, was accomplished at a Boeing plant in Kansas. In February 1949 a B-50 named “Lucky Lady II”, piloted by air force Captain James Gallagher, flew around the world nonstop, via aerial refuelling, in eighty hours. All of these large planes pointed to the wide-bodied commercial passenger jets of the 1990s.
