I wasn't personally, but I have no doubt it probably happened a number of times whether the GA driver knew it or not!
I was in and around Tindal from '80 - '85 so it was not a permanently active base then. Pitch Black exercises were always a fun time from watching some impressive acts of aviation like sitting beside the runway watching quick circuits in the Mirage, exploding F111 engines one year or just strolling across the threshold past the fast jets (and the not-so-fast Caribous!
) for dozens of very cheap VBs in the mess.
