I too watched the F-4 practice at Finningley the week before and was worried by what I saw during a loop. The pilot definitely appeared to push the nose up whilst inverted, without gaining height, or perhaps even descending a little. As the aircraft bottomed out, pulling a lot of G, it began wing rocking. I never flew the type but did know that this was a pre-emptor of the type departing from controlled flight.
I was very sad to hear the outcome of the BOI.
