16 Facts About Boeing 707

Boeing 707 is an American, long-range, narrow-body airliner, the first jetliner developed and produced by Boeing Commercial Airplanes.

Boeing 707 had produced innovative and important bombers, from the B-17 Flying Fortress and B-29 Superfortress, to the jet-powered B-47 Stratojet and B-52 Stratofortress.

Boeing 707 had produced aircraft that were not as commercially successful as those from Douglas and other competitors.

The 400-, 500- and 600-series were already used by their missiles and other products, so Boeing decided that the jets would bear 700-series numbers, and the first would be the 707.

The marketing department at Boeing chose 707 because they thought it was more appealing than 700.
