20% of the people who take a trial lesson decide to have flying lessons.
That seems a little on the high side, bearing in mind the number of people who turned up at my old flying club for a trial lesson. I asked the question once , about how many people continued after a trial lesson and the answer was 2%.
It would cetainly be interesting to get some definitative figures as to the drop-out rate in the UK.
I'm a Anorak, but collecting my Elite Anorak badge very shortly.
