Aerobatics

There was an aerobatic show at the beach today. They started off with skydivers, two sticks of two with square chutes and smoke canisters on their feet to make the maneuvers more visible; all four landed, one at a time, on the beach in front of us. After that the stunt planes started coming in. We saw tumbles, an octagon loop, hammerhead stall, and in intentional inverted flat spin, which is not something I'd ever care to try. However...after half an hour or so, you've seen the same maneuvers done by three different planes in a row, and it didn't seem worthwhile to sit out in the sun and watch it for another two hours.
