SilsoeSid, I did say I didn't know much! I didn't get taught that way of steering as a civvy, and I suspect that very few outside the military do - after all, most of them aren't required to fly below what I was taught was hover height.
The difference between a car and a helicopter is that the car is always touching the ground, so whichever way the wheels point, the car goes. The NOTAR can fly sideways and backwards at 40 or 50mph, so whichever way it's pointing isn't necessarily the way it goes.
