I can't say I see the problem, if I'm honest.
My time instructing at a UAS I found a joy, both the flying and the social aspect.
I maintain the time spent in the cockpit was conducted with the utmost professionalism, but on the ground - being a red-blooded male, I suppose I must confess to hanging out of the back of a few myself...
Its not as if they put up a fight or showed any objection, most were in fact rather welcoming, and after all, they were all at least 16 from what I gathered.
What seems to be the problem? A private can marry a General, so why can't an instructor go through a couple of cadets??
