It's a good thing he's never fallen to his death and thereby been given a reason to have a terror of heights. Oh, wait.

In all actuality, Andrew isn't so very frightened, though of course there's the natural human (and, alright, Time Lord) tendency to imagine himself plummeting to his death from the heights they reach. With Secret strapping him down and Daine between him and the open air, though, it's not so bad -- like riding a reverse hang glider, if hang gliders were sapient.

"Do you do this often?" he calls over the roar of the wind. He's got his hands wrapped around a couple of feathers without really meaning to do so, probably pulling or pinching them uncomfortably.
