London Mayor Boris Johnson says it's too early to draw any conclusions on whether there should be more restrictions on additions to the capital's skyline
"What we're going to be doing now - the Air Accidents Investigation Branch of the CAA is going to be looking at all those kinds of questions''
"Was that in any way responsible for the crash? Clearly, we'll want to study that and form our conclusions. I think it's all a bit premature, frankly."
The Mayor was speaking in Croydon, south London, after announcing a £1 billion investment for a redevelopment plan in the area.
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.
