Didnt guys in the old days allow a kid on the flight deck to transmit a radio call or heaven forbid, twist the heading bug.
"The old days!"
It was only 10 years ago! (Although I see your profile says you are "3"
)
I once had the 18 year old daughter of one of the local controllers on a flight. He contacted us, and asked if she could visit the cockpit (he would be in the tower that day). We sat her on the jump seat, and had her make the ground calls for clearance and taxi (she read them from a bit of paper) to her father, who answered. Many chuckles and giggles (and queries from other planes), and we departed. Had a nice short cut and straight in approach on the way back in thanks.
If you can't have the odd day of fun at work, is there any point ?
Many times had children visit the flight deck, and "turn the aeroplane" with the heading bug. (Pre Sep 11, obviously.)
