Woman leaps from burning building in London

This amazing photo, showing a woman leaping from a burning building in London, is doing the rounds on Twitter. It's hard to verify, as the website of credited photo bureau Wenn is down, for what may be obvious reasons. Some are claiming the signs suggest that the image is actually from the U.S., not London, but those are almost certainly Croydon tramline signs.

Update: The photo is posted at full size in this Mirror story. Bad Science's Ben Goldacre also posted a tramline sign photo.
