Nearly off thread but related.
Many years ago, I flew skydivers and the guy I flew for was always in a hurry.
Anyhow, he got out of the 206 and shortly afterwards there was this - Thud !
He had walked into the back of the wing.
Much profanity, however, when he re-appeared, I had to bite my knuckle because there was a row of diamond shaped indents right across his forehead.
Oh my how we laughed.
And the other one was when I took my lad to work at the airport for a look around. All great - he was about 6.
Came back to the parking lot, I walked past the barrier....... again, there was a Thud.
He walked straight into the barrier and was now on the floor.
Well - what is a dad to do ........ ?
ROFL
Don't think he ever forgave me.
He's 27 now.
