The wind was a NE'r but it does tend to often twist/gust more North up near the runway. I think also because the big zoom and depth of field it skews the perspective a bit. maybe the plain was just taxi'ing. The weird thing is that I don't even remember seeing the plane must have been concentrating on the sailing.
It's funny sometimes you can have 4 or 5 planes sitting there waiting for take off. So you know that there are a few hundred people watching you and you start thinking will I drop this gybe, the pressure is on!
