Please don't be rude about the JP3.
Damned thing nearly killed me one day during my BFTS course, but my fault and ham fisted-ness. Stuffed up a stall turn, nose was too low to begin with, so tried to correct it at the point of the stall and presumably had some up elevator. It did something I hadn't seen before; it flicked in the vertical then fell out backwards into an inverted spin. Thankfully, I recognised it because I had previously seen one of those in a Cessna 152 some years before. However, having finally sorted it out (eventually recovered it but then it spun upright going the opposite way) and climbing I realised I'd gone considerably below minimum ejection height for the seat. Lost over 10,000 feet in the process. Having recovered my composure by flying straight and level for a while I RTB'd to Linton. On reporting it to my instructor, in so many words all he said was "Well don't effing well do that again!" Lesson learned!
However, I did later wonder if it was ALL down to me after John West (ex Harrier display pilot) was killed in a JP (actually a Strikemaster), in similar circumstances during a civvie demo flight to a potential buyer.
