con-pilot:
We did dry lease quite a few 727s during the years I was there and I do remember one was an ex-TWA bird. Also, we leased one that was the old Hoot Gibson aircraft, that aircraft wanted to fly sideways more than it did straight.
The "Hoot Gibson" bird was a -100 (-31 type for TWA). I flew it shortly after it was repaired and returned to the line. The F/E took me down to the ramp to show me the still visible ripples on the aft fuselage. Ugh!
