Deep stalls, T-Tails
Not 1-11 but a related question occurred to me lately, a friend was involved in the stall tests on the Trident; he was a chum of George Errington's, and we know that sad story...
My chum described taking the Trident to within 1 degree of the Alpha limits, he reckoned it had 'very precise handling' - when I asked if he had a specially calibrated guage he looked blank & shook his head !
I have my own guesses as to whether this was wise, but does it even sound feasible to you Test Pilots out there ?
