The mob that presently employs me sends us to National Test Pilot School at Mojave every 3 years for upset and formation review. A day of ground school and a couple of flights in an Impala. Aside from making the Tweet look powerful--very instructive. I hadn't done any acro or form since leaving tac fighters, but surprising how quickly recovery skills came back. The profile is stalls, spins and lots of UA recoveries--set up and "self-induced". The non-military types that hadn't done any acro really benefit. No, in one flight no one learns much about formation except some respect
