I was on the staff at Thorney at the time, the Capt and Nav had only recently passed through the OCU (not sure about the remainder of the crew). As Brian says, questions were asked about the planning of the exercise and the wisdom of having a night stream so early on. As I recall, it was also the first time the crew had flown a night low level formation, so there were suggestions that it should be included in the OCU tactical phase, but I dont think that happened. A lot of the troops felt that someone 'higher up ' should have been held to account, and that the BOI was a bit of a whitewash. I dont know the rights and wrongs of the situation but it certainly caused a lot of ripples at the time.
