Oh yes Brad does play a role .... apparently "The Major", would have given both of his man glands to have WA associated with Brad. Whilst he and Angelina (oh god, what a babe) where in Namibia, Brad had some flying training in a Grand Van. Seeing that WA had a Van at that stage based in Swakop, "The Major" would have liked to have WA's instructor do the training. He even approached the instructor, inviting him and Brad to have tea at his place. According to Brad he did not have time or the inclination for social visits. After all they where in Namibia to get away from it all. When this tea party did not happen, the s...t obviously hit the fan, "The Major" was unhappy and somebody guilty, or generally undesirable, had to be found.
I believe the Brad thing was perhaps not the direct reason for Fridays boxing session, but surely added a couple of drops to the proverbial bucket.
Apparently his words (before the first blow fell) was something in the order "... stop harassing my pilots ...."!
