Helicopters Flying Through Tower Bridge
A delightful evening in London spent watching a pair of helicopters fly through Tower Bridge.
It appears that it's part of the London™ 2012© Olympics® opening ceremony.
First, the practice run:
Then the three flights through the bridge
Thanks to IanVisits for alerting us to the event, and Tom Scott for organising the picnic.
It looks like you've embedded the first pass twice, as first and third.
Thanks. Corrected.
