Quote from Jackonicko (my underscoring):
"I'm not sure that the graphic bears enough resemblance to the manoeuvre seen in the videos, which seemed to show a roll to starboard during the climb, resulting in an approximately 90° change in heading."
Have to disagree, although that's what it looks like also to me on the most-shown video taken from north-east of the airfield. But, when the Hunter appears later, going over the top, you realise that in fact it must have rolled to the left during the climb. That is backed up by the other video taken by someone standing by the A27 near the subsequent crash site. (I frequently misjudge the direction of roll when observing a/c from the side at airshows, and it looks like I'm not alone in that.)
