This is a video shot at the hamilton airshow this past summer I believe with some very very good footage of the lancaster, a mosquito (I think this is the one just rebuilt in australia and now based in the US) two hurricanes and a mustang.

TEN merlin engines in formation!   a must watch video IMHO

However it is 45 minutes long, so plan on watching this when you have the time to enjoy it.  GOPRO photography at it's best!
