Hey, now wait a minute. 15 years old? Isn't this regulated somewhere that you have to be 18 to learn to fly? Or can just anyone, at any age, with the bucks, enroll in a school?
Did he get all his ground-school training at the school and practice "flying" via Flight Simulator? How was he able to get his paws on that plane?
16 to solo, any age to take dual, but those low are "record" flights are outlawed.
