Jetstream 61 was the real deal.
This was the ATP mk2. It was what the ATP was supposed to be if it had been given the time to be developed properly. Better engines, pressurisation and the toilet moved to rear.
So what did BAe do? Flew it once for 1 1/2 hours then chopped it up because of AIR/ATR. Typical.
BAe refused to prove a cargo door on the ATP 9 years ago. Now most examples have been converted to freighters. Again typical.
