In what way have they failed?
You're obviously new to this thread and the sorry saga of how a whole fleet of aircraft, much enjoyed by thousands of kids, was taken from them with NO REPLACEMENT provided.
I know its 258 pages long, but please go back and start reading this thread from the start. If you can't be bothered, or don't have the time, just read the FOI's detailing how people basically sat around drinking tea and smoking fags while they should have been overseeing the airworthiness of the most basic of aircraft.
They took decisions that you didn't like.
And neither did anyone else. In fact, the only people who 'liked' the decision, were those handful who had an awful lot of arse covering to do!
