Sleeper
Your quite right I haven't flown everything in the airforces inventory just a mix of whizz jet and multi.
The nose high speed rapidly blah blah thing was purely out of interest rather than an attempt at a recommended technique for a Boeing. Both you and RAT 5 are quite correct it will take quite some height to recover and quite probably more than this crew had available although it is equally possable it would work depending on trajectory, attitude etc.
In the real case all you can do is follow Boeings recommended stall recovery.
Agree with you RAT 5 it would be very interesting to see the FDR.
