In my experience flying training in the RAF was not an enjoyable experience - everything was tense and the fear of the chop was ever present. Some instructors seemed to take delight in making students life miserable.
Stupid really - as everyone performs and learns much better in a more relaxed atmosphere.
My first instructor on Vulcans was great however - my first attempted roller landing was a shambles when the runway disappeared from view - he calmly took over and whispered - try raising the seat and have another go !
Later on when instructing Air Refuelling the odd reminder to relax and keep breathing usually worked well.
