Not military but I have a son who is just starting his second year of holds. It is a disgraceful waste of taxpayers' money and, allowing for the inevitable fallout during training, probably means that we pay to train two to three pilots for every one needed. It is time the MOD got their act together and sorted this ludicrous system out. No business would accept such a waste and survive.
Sorry, just ignore me, but I feel better having said it.
