I was watching some of the 750MC racing at Rockingham this morning.... from 2,000ft.
A friend took me for a microlight flight this morning and we just happened to fly over, we saw some cars going round, got home and checked and it was a round of the 750MC.
I did wave to all the locostbuilders members down below. I didn't see anyone wave back though.
We were warned to look out for the Red Arrows as apparently there was some other motor racing event on a bit further south. Didn't see them though.

we would of waved but were a tad busy racing or at least trying to between red flags
