In a UK pilot supplies shop a couple of years ago a walk in bod asked for 'one of those maps with aeroplane things on'. Assuming (correctly) he meant a Southern England half-mill I sold him one, and asked his interest. He explained he had bought a paramotor for a friend who had given him some basic instruction, and flew it out of his field some way South of Oxford. I asked, out of interest, how high he went and he indicated that the highest his barometric watch had said was about 8,000ft. I pointed out the various restirctions and heights for his education. So if you fly an airliner, and meet a paramotor in the Northern TMA, it could be our customer, in spite of advice.
