Mayor vows wide-ranging review
Mayor of London Boris Johnson said lighting of cranes and tall buildings will be reviewed, but that it would be "premature" to second guess the investigation into the helicopter smash.
Speaking on a visit to emergency services working at the site of the crash, he said the review was "inevitable".
"It's a bit too early to draw conclusions from this accident about this or that tall building. What is inevitable is that we'll want to review all our policies, we'll want to look at the way we illuminate tall buildings, the way cranes are illuminated, to make sure nothing went wrong in this case and make sure nothing goes wrong in the future," Mr Johnson said.
Questions were raised about the brightness of safety lighting on the crane being used by construction workers building a tower block near Vauxhall Bridge.
The crane was clipped by a helicopter, sending the aircraft smashing into the ground.
Mr Johnson added: "There are all sorts of questions that people are asking now about tall buildings, about lighting, about the fog, about the usage of Battersea heliport and those are very understandable questions in these circumstances.
"People will naturally want to know that we are doing our level best to make sure that London is protected from aviation accidents of this kind.
"Those are matters that are now being investigated, it would be wrong for me to pre-empt any of that."
He said it would be premature to guess what investigators may find.
"This is going to be the issue that people will want to discuss. They will focus on traffic going into Battersea.
"I really think it would be very premature at this stage to second guess what the Air Accidents Investigation Branch say."
The Mayor said it was clear that the accident could have claimed many more lives.
Describing the scene he said: "It's a tragic scene of the wreckage of a carbonised helicopter and of course a great deal of damage done to an adjacent building. It doesn't take a great deal to imagine what could have happened had that helicopter crashed into a bus or a heavily occupied building.
"Obviously our thoughts are very much with those who have lost their lives, their families and all those who have been injured, but it is also true that it could have been much worse."
He said that workers at the scene were now "very confident" that the huge crane was now secure.
