It's a little early, I know, but I just saw this on the BBC news site. It's the Red Arrows Synchro Pair practicing their "heart" maneuvre for Valentine's Day over Lincoln Cathedral.
I watched a great documentary a while back about the Red Arrows and now it's on YouTube here. Even if you don't want to watch it all parts 5 and 6 are pretty cool, if only because the Red Arrows guys are amazingly understated when they turn up for the Quebec air show compared to the Thunderbirds and the Blue Angels. There's discussion, perhaps even gentle mocking, of the 'spray on flight suits' that the Blue Angels wear compared to the rather more roomy suits the Arrows wear.
