I remember "How many hours to first solo ?" being asked on one of the hundreds of job applications I've filled out over the years. Obviously they wanted to gauge basic ability.
I had about 14 hours altogether in my log book which was spread out over a period of time. It would have been a bit less had I started with a couple of weeks free time and sufficient funds in the account, arse covering was far less important in the 1980s.
Longest I remember was 83 hours to solo and 160 to PPL, determination won in the end.
