On the ATC bit, lots of people seem to assume that Air Traffic Controllers have some role in controlling the aeroplane (I heard a rumour that most of these people have now got jobs as instructors at a well known flying school).

Asked while winding up the elastic in my Cub:

Q Is the starter broken?
A No I'm fine thanks

He proceeded with:

Q Where's the stall warner?
A In there in front of the seats.
Q Where (peering into the cockpit)?
A There, that stick thing poking out of the floor, when it shakes I move it forward.

Q Where's the radio?
A In my car (meaning my handheld)
Q How do fly without a radio?
A Usual way, the wings seem to lift the whole thing off the ground.

He finally realised I was extracting the urine slightly but took it in good part. His experience was with PA-28's up to then. He did seem interested enough to expand his horizons though. I hope he did.
