Sir Richard
during my conversion on to the VC 10 it was demonstrated what happens when you use differential braking at low speed with a large tiller angle - the warning horn went off to say that the nose wheel had disconnected from the tiller.
Fortunately it hadn't gone too far and the skipper managed to get it reconnected without calling for a tractor in the neck at Man.
The engineer and I had a good laugh as the regular copilot and the skipper had "history".
I never had the misfortune of flying with them again.
