Abagnale,
Fair comment to some degree....clearly it does say something of your ability if you need 50 extra hours to go solo for the first time...but I would strenuously defend that going first solo at 20 hours means absolutely cock all in the wider scheme of things, as opposed to 15. In the same context, someone who goes first solo at 10 hours as opposed to 15 is not necessarily a better pilot.... For example, I took a whole half hour longer than I should have done to go first solo....does that make me any worse than anyone else, even though I passed CPL/170/IR first time in min hours afterwards?
If you've done 50 hours and STILL not been sent solo, then yes...you hsould perhaps consider whether you should continue pursuing this as anything other than a pastime..
