Quite interested to hear why a 17 yr old should not be allowed to fly an aircraft with passengers? If he's got a licence, he's proved he's capable of doing so.
I'm 17, gained my licence of my 17th bday, and took my parents and sister flying on that day, back in July of last year. Have since taken over 20 friends and family flying, as they understood I'd been through the approved courses and proven I was suitable to hold a licence!
