One of the joys of being the Theatre Ground Runner (or MTP if you like) was having to test the Jack stall entry and recovery characteristics on every Gazelle MR Handling Check. Suffice to say, having got several dozen under my belt, it rarely surprised me but I also discovered many line pilots were often surprised and unaware of the correct technique. Just like Fenestron Stall in fact, which is simply a French phrase meaning "Lead-Footed".
