The RAF used Chipmunks for ab-initio training for direct entrant pilots up to 1993. One of the reasons (apart from that it was an excellent elementary training aircraft - the best I have instructed on IMHO) was that it was a handful on the ground and would sort out those who were going to make as RAF pilots - or not.
Groundlooping was common and many students did it. I must have seen about five from the rear seat. The aircraft was so strong that it coped. The ground engineer's post groundloop check was a cursory look followed by "It's OK".
As about half of the RAF pilots trained between 1984 and 1993 went through EFTS at Swinderby, there are more tailwheel trained pilots out there than you would probably think.
