One of my jobs was to help identify or eliminate one of our aircraft as the other aircraft in a near miss. What amazed me was that every potential crew could give me their precise position for the incident time even days later.
One such incident was an airmiss at night during a major air defence exercise when a window of a light twin was sucked out as it flew at lower levels on the Blue way. One of our F3 was in the frame. They were able to day that it was their target that had the airmiss. It was certainly a sheer terror moment for the civvy, I don't think the other knew.
