I've been playing with Google Video
The USAF displayed the B2 Spirit Stealth Bomber at the 2003 Royal International Air Tattoo, RAF Fairford, UK. It flew non-stop from its base in the US, circled the airfield once and then flew straight back. Unfortuntely it was accompanied by 2 fighters and the show decided to play background music, so you couldn't hear how silent it was, but it was still an impressive sight.
Taken with a Canon S45 so it's not great quality, but you get the idea.
