Ahhhh shit, I can't see there being any survivors on this :( It came down in a residential area too.

Edit: apparently a guy sat in 11A survived?!

On a video posted to Reddit you can hear the Ram Air Turbine running, suggesting there's a hydraulic / engine problem. You also don't hear the high pitched whine from the engines you'd expect if the plane were taking off normally.

Also, Air India goes by the unfortunate initialism "AI", which will really gum up the headlines here.
