Thats right JGC, it was the Day Fighter Leaders School though to the best of my knowledge it was not an aerobatic team.
The school would have been too busy to indulge in that sort of activity.
They were on a normal training sortie and were caught out by a deterioration in the weather, but depending on who tells the story there was more to it than that.
Whatever, it did cause something of a stink and the sudden posting of certain gentlemen in authority.
