besides, if we were to start in 1955 as i sugested, the DC-3 would be small...the 707 and most other 1st gen. jets will be out (as well as the much larger prop-liners like the Connies and B377), efectively dwarfing the DC-3 in the way that a 767 dwarfs the ATR-72....
In 1955 there weren't any jet airliners flying in commercial service.
- The Comet had entered service in 1952 but had been grounded in 1954, not to re-enter service until 1958.
- The Tu-104 first flew in mid-1955, but didn't enter service until 1956.
- The Caravelle flew slightly before the Tu-104, but didn't enter service until after the Russian jet.
- The Boeing 367-80 flew in 1954, but it was simply a technology demonstrator (NOT the 707 prototype, as many have incorrectly stated).
- The actual 707 prototype didn't fly until late 1957, and the 707 didn't enter service until 1958.
- The DC-8 didn't fly until 1958, and entered service in 1959.
