Channel 5's documentary about train company First Great Western included a section on this years (2013) air show. If you didn't see it you can watch it on demand 5.

What an excellent advert for the town, well done Air Show and well done First Great Western.
Watched it last night. It has been a fascinating series and has featured the sea wall section a few times, but last night was a great showcase for Dawlish. Beautiful blue skies, lovely beaches and a great airshow
