Tributes have been paid to a pilot who died when a helicopter crashed into a crane in London.
An investigation is now under way into how Capt Pete Barnes, 50, hit the crane on The Tower, One St George Wharf, in South Lambeth on Wednesday morning.
A second person who died on the ground is believed to be Matthew Wood, 39, of Sutton, south London.
Mr Barnes had flown for Redhill firm Rotormotion for 15 years and colleagues described him as "highly skilled".
Cars and two buildings caught fire after the burning wreckage fell into Wandsworth Road.
Five people were taken to hospital, one suffered a broken leg while the others had minor injuries.
Capt Philip Amadeus, managing director of Rotormotion, said: "We are devastated by the loss of a highly valued colleague and very dear friend.
"Our thoughts and condolences are with Peter's wife and children."
The experienced pilot, from near Reading in Berkshire, who had amassed 12,000 flying hours, had asked to be diverted to a nearby heliport because of bad weather.
BBC weather centre said observations at the time showed very low but not thick fog.
Kevin Hodgson, director of operations at the Great North Air Ambulance Service, worked alongside Mr Barnes for several years, flying on life-saving missions across the North.
"Pete was as good a guy as you can imagine and one of the best pilots I've ever had the pleasure of flying with," he said.
Mr Barnes also flew for the Derbyshire, Leicestershire and Rutland Air Ambulance Service.
Derby Hospitals NHS Trust tweeted: "Very sad to hear tragic news of death of air ambulance pilot Pete Barnes, he made many visits to our helipad at Royal Derby Hospital."
Metropolitan Police Commander Neil Basu told BBC News it was "miraculous" the crash was not much worse.
Five people were taken to hospital. Seven people were treated at the scene.
Falling debris
It is thought some of the injured were hit by falling debris.
Tony Pidgley, chairman of site developer Berkeley, said the crane driver was not in the crane because of the "fog level".
"The operative is just not allowed up that crane in conditions like that because you just can't see," he said.
Part of the crane was left hanging from the side of the residential building, which is still under construction.
London Fire Brigade said part of the tail section of the helicopter landed on the roof of the building and the main section landed in Wandsworth Road, hitting two cars. The fire from the helicopter ignited two buildings.
