I was there - but it wasn't me. I don't remember the previous exchange officer's name, but I remember his last trip!
I was debriefing with the staish, when the first pass rattled the roofing felt. He (we) stormed out to see the jet, at what appeared to me to be eye level, coming across the airfield straight at us. Another impressive beat up followed. The staish demanded to know who the miscreant was and, when told, decreed that that was to be 'his last flight on my station!'
