I loved the Constellation! I got to fly it one time from NYC to Hartford Conn. My mom was a "Stewardess" during the 40's for KLM and that was the plane of choice. Beautiful plane. I believe there is one in Apopka just sitting out at the airport in Florida, and another at the Boeing museum in Seattle.
They lost a lot of engines coming from Europe over to NYC. She had a few scarry experiences, and also lost some dear friends.
