Battle of Britain - Guernsey 2009.
This particular occasion was not the worst weather we've had - it's been cancelled several times(!) but the conditions were not great at all. Most people will travel to Jersey for their display which, being better sponsored, is several times better (usually) than the Guernsey one with more classic and interesting aircraft than usually attend the Guernsey display. Unfortunately, the flight lines for both displays have been moved further and further away from the sea wall (the closest one can get to the action) over time so good photography isn't easy with standard lenses.
