Fledge from the Ledge.
"It's a looong way down and I don't know if I will master this flying thing on my first attempt.
"Why couldn't mum lay the eggs a bit nearer the floor?
"If I cling on tight and flap my wings just to see if they will carry my weight, first. Can't be too careful.
"OK! I've read the flight manual, wings seem alright and I can move all the controls.
"On Three, chocks away!. One. . . . . . . Two. . . . . . (Wait for it) . . THREEEEEEEEEEE!"
