Oh, the School was Dalfort, the former Braniff training school.
Small world
Con, that's who administered the B727 maintenance training course I attended back in about 1992. Though I was working on bizjets like Jetstars and Falcons at the time, several of us were sent to this school in preparation to bring an ex-Lufthansa -200 out of long-term storage and return it to service. That turned out to be a couple of months long project for about 10 mechanics. That old three-holer still had the nosewheel brakes plumbing installed as I recall. It had the oval #2 eng inlet as well. (some -200s did and some didn't)
But back on topic. On the IAI Westwinds I flew, there was nothing preventing the reversers from being deployed in flight. When deployed in the landing flare a couple of feet off the runway, a firm arrival is likely! Inadvertent deployment of one reverser during takeoff was a common SimuFlite sim training exercise and the source of much fun. Actually you could fly away from the ground like that in the sim scenario with aggressive and timely rudder input, but I'm happy to say I never had to in the airplane.
The CP at one company I flew for had an inadvertent deployment during a checkride while doing 320 KIAS but managed to regain control before it got too far out of hand. Not only wasn't the offending T/R ripped off the airplane but there wasn't even any damage. None. Tough old beasts.
