The man killed on the ground in the helicopter crash shouldn't really have been there. His family told ITV News London that Matthew Wood from Sutton was only walking through the Vauxhall area when the helicopter came down yesterday, because he liked to get to work early.
But a crane driver probably survived because he overslept. Ronke Phillips spoke to Matthew Wood's sister.
The pilot of the helicopter which crashed had thousands of hours of flying experience including for films such as Die Another Day.
The crane operator only survived the Vauxhall helicopter crash because he was running late and had not reached his cabin.
Air investigators will seek answers to a series of key questions as they begin their inquiry into the London helicopter crash today.
