First U.S. jet international passenger flightIn 1950, the first U.S. jet passenger international trip was a flight from Malton Airport in Toronto, Canada to the International Airport, New York City. The Avro Canada jetliner carried a crew of three, with three passengers, and 15,000 airmail letters (which became the first airmail letters carried in the U.S. by jet plane). The 359 mile flight took one hour, powered by four Rolls-Royce Derwent jet engines. |
