Yes, roving. Indeed I knew Frank W fairly well ... I have a couple of photos of him in my albums. A very sad event, and IMO un-necessary. I could add other comments, but that would be disrespectful.
At the time there was an opinion that he tried to fly it out of the super-stall using power, instead of just grabbing the stripey handle. I am in no position to comment on that.
We lost a few, although thankfully less than a handful in my time. Peter (?) T was the only other fatal I can remember (reheat bay fire, ejected too late downwind on his first F.6 trip on 74). I had met him for the first time the night before.
Athough a few bent airframes did occur on or adjacent to the airfield ... including Pete Squire’s VERY late ejection over Tengah Village when I was doing Local. His ‘chute deployed just as he reached the tree-line. As he said in the Bar later, “The chute deployed, the harness snapped, my visor dropped down, and as I reached up to lift it ... I hit the ground.”
