Those hi-res pictures just send shivers down my back. Let's pray to whichever entity we believe in that everybody got away with this one, and the only casualty is related to Mr Boeing. The tail section looks the worst. Here's hoping.
It seems not unlike the 777 at Heathrow, albeit a lot further out from the threshold. Windshear? Seems unlikely if no one else reported it. Fuel starvation/contamination? We'll find out in due course.
