Air accident investigators are probing yesterday’s helicopter crash in central London which killed the pilot and one other person on the ground.
However, it could be months before the Air Accident Investigation Branch get to the bottom of what caused the tragedy, which happened in the busy Vauxhall area during the morning rush-hour.
There have since been calls from local residents for helicopter flights over central London to be restricted.
The Civil Aviation Authority issued the following statement hours after the accident: "Helicopter operations in central London are strictly controlled.
"Single engine helicopters are required to fly along designated routes, which have been selected to provide maximum safety by routing helicopters along the river Thames, avoiding flying over built up areas as much as possible.
"Twin engine helicopters can operate in wider areas, however all aircraft operating in central London are subject to air traffic control clearance.
"There are requirements for lighting on tall structures. In addition, where appropriate, very tall structures are also notified to pilots for flight planning purposes, as was the case with the crane that was involved in this morning’s accident.
"The independent Air Accidents Investigation Branch is now investigating today’s accident to establish the facts. The CAA will be providing any assistance required."
In January 2012 there were approximately 1300 helicopter movements in central London
