Mind you, having a good idea of who trained Gertie, I wouldn't actually put it past them when bored...
All gone, that old school of instructors, I'm afraid.
One of my favourites was the low flying lesson - "imagine you've stupidly got yourself stuck below low cloud in low visibility, right, descend and slow down, let's have some flap, that's it, now keep going low and slow".
"What about that row of trees?"
"Look at them carefully."
"Oh ... you want me to go through that gap?" (At which point I realise that this is a game he has played before at this carefully selected location.)
Through the trees.
"What about that row of pylons and wires ahead of us?"
"You can't see them yet. We're pretending we're in low visibility remember."
A bit later.
"What about that row of pylons and wires ahead of us?"
"You still can't see them."
A bit later.
"What about that row of pylons and wires ahead of us?"
"Oh, do you think you can see them now?"
"Yes I ****** do."
"Oh all right them. OK, I have control, don't try this on your own."
Full power, low speed steep turn, and you can imagine how high we weren't.
