I have to get my usual bit in here
Even if many pilots don't realise this at the time, one of the great attractions of flying is to be able to fly
abroad, and to do so in far less time than it would take to drive. Flying abroad is a great pleasure and is usually far easier than flying in the UK; for a start you get away from the machine-gun-speed ATC speak. You can fly all the way across France and not see another plane.
Can't do that on the NPPL.
Most PPL-level flying in the UK is done on routes which one could drive in a comparable time. And what percentage of PPL holders give up before the first renewal?
