Hi con-pilot...
I only flew the 727-276 with -15 engines and the 727-269 with -17R engines, and both of these were really great airplanes.
Those 3 x 727-269-17R we flew are now (since '94) being operated by SyrianAir.
I was then with Kuwait Air and delivered 'em to Damascus, then stayed for a few weeks to train the local 727 crews on the very latest model (built in '84) of the venerable 727.
A really great airplane.
Cheers...FD...
