The first powered aircraft flew in the 1900s, and by the 1940s we had jet aircraft. The Boeing 747 was introduced in the 1960s, and in the 1970s we had supersonic flight. The pace of innovation has stalled since.

- dredmorbius 7y agoI suspect commercial supersonic flight was meant. Concorde was testing by 1969, but didn't carry passengers until 1976. The USSR's Tu-144 actually beat Concorde on both dates -- 1968 and 1975. Though it also beat Concorde, by 25 years, on retirement from passenger service: 1978.
