And the top line turns green for a bit, while all the rest is yellow. Apart from an orangey section around the figure of eight. I can't think of anything except altitude that might have signified that.
I'm still puzzling over the squiggly corners, rather as if somebody was passing through a stile. Handheld launch of a grounded drone, possibly?
Great quiz, Chris!
