Re: Planes Trains and Automobiles Movie

Just how far was the rental car lot at STL? :) That lot was parking for the current terminal 2. I believe it was long term parking at the time, just across I-70 from the Stouffer Concourse Hotel (now Renaissance). I was going to Parks college in Cahokia when the movie was shot in STL.

A few are in the 42,000 cycle range. Limit of Validity is 50,000 cycles. Previously retired 757s were scrapped at around 45-46,000 cycles.

Early AA 757s were scrapped with only 25,000 cycles.

It will be interesting to see what RR will do with the -524 now that BA is out of the game. Granted, Cargolux is an original operator of the engine and they should still keep supporting those airframes. The PW4000 and GE CF6 both have military applications that will keep them around for decades.

It’s a 767. The 757 does not have a nacelle strake. Pylon looks like a PW4060. If it had a domestic interior ( standard F/C seats), it was probably one of the domestic ETOPS ships 1401-1404 (all now scrapped).
