It is good to see that this case ended with the correct result. Nik, for all his previous contributions to Hawkwind, should have moved on long ago and made a career for himself. Sadly, he could not do that and has turned into a bitter person.

An aileron roll carried out by a pilot as a sign of victory or celebration is known as a victory roll.

This is a manouvre between a wing over and a barrel roll.. It is dangerous!

What could sound easier than applying full aileron until a 360o roll is completed? The problem stems from the rate of roll of the aircraft and where the lift vector is pointing. Most aircraft are designed to fly upright so, when the bank exceeds about 75o the nose will drop - the aircraft is behaving like a dart with the added issue of yaw into the dive (secondary effect of the ailerons) - and without corrective action the nose will be close to vertical by the inverted position. High 'g' is required to recover and the aircraft risks a spiral dive or overspeed (Vne).

One way we can improve matters is to raise the nose to, say, 20o nose up before starting the roll - this will work if the aircraft has a high rate of roll but any mistake, or loss in power, and the aircraft is going down big time... As high nose up entries, and lots of 'dish-out' can result these are best done at height.
