We had one of the TWA -100's and it was a pain in the @ss as it was differen't from every other one we had. It was also the only one with the early pressurization panel.

All in all the 727 was a really nice plane. Especially comming from the DC-8 which was a really horrible plane to fly.

The 727's we had were freighter conversions and actually had most of the insulation removed to save weight so it was louder than normal and very cold. The 72 cockpit is not a quiet place.
