BAC One-Eleven crash on test flight. Deep Stall
The F-28 and F-100 also had an escape chute to the side of the aircraft, but fortunately these aircraft did not suffer from deep stall, and the cute was never used. Also, JATO's were installed in the tail to push the nose down. Also never used. Fortunately.
I have a feeling East African Airways had a stall related incident (though it may have been a yaw damper Dutch Roll event) on an air test of a VC-10 over the Indian Ocean off the coast of Kenya.
I can't find my copy of "East African - an airline story" by Peter Davies, in which I'm sure he describes it. I believe it came close to a tragic conclusion.
BSD.

You use an F.28 Mk.100.
Edited to add: I had a look through my copy of Peter Davis' book, but couldn't find the VC10 stall incident BSD mentioned. I would be interested to learn more about if you can find the details.

The 10 prototype G-ARTA had an eventful early life doing stalling tests for the type. It was on one of these that as BT put it 'All h... broke loose' and he thought they would loose the machine.
Not sure of the sequence but two engines 'rotated' in their mountings causing associated loss of hydraulics and instumentation, one elevator went unstable and all in all it was obviously a very alarming situation. This is the flight where they tried to operate the escape hatch.but when fired the trunking inside collapsed. After slowing down to near the stall speed the elevator calmed down and they were able to 'drop the gear' and return to Wisley. The poor old girl had done hundreds of stalls and was probably lucky to survive.
Survive she did and went into service with BCAL but was severly damaged in a landing accident at Gatwick 28 01 72 never to fly again, no doubt having spent many years in the Aviation eqiv of PTS. I would highly recommend this book to anyone wishing to revisted the time when flight testing had to be done before simulator experience available.
