Many thanks to Anders for hosting this week. A cool theme, I'm hoping to see some great action-captures. I had to search through my archive, as action-shots are not something I do a lot of, but managed to find some!!
Here are mine:
1) Leaping Dolphin, Seaworld, Florida.
2) Riders on the Montu rollercoaster, Busch Gardens, Florida, go through a barrel-roll.
3) I took this shot of a British Airways 747 at Windsor Castle, which happens to be under one of the outbound flight-paths from Heathrow Airport.
4) This shot might look blurry, but it contains quite a lot of action. I was driving through a rainstorm, you can see the rain on the windshield, along with the windscreen wiper in motion.
