The chopper which crashed during the London rush hour was registered to respected helicopter firm Castle Air in Liskeard, Cornwall.
Castle Air describes itself as the UK’s “premier helicopter service” and has been operating since 1979.
Its choppers are used to transport VIPs and also specialise in aerial filming with credits including Treasure Hunt, Top Gear, Time Team and Robbie Williams’ ‘Angels’ video.
The firm mostly flies twin-engine, eight-seat Agusta 109 helicopters – like the one that plummeted into the ground in Vauxhall.
The helicopters have been built by the Anglo-Italian manufacturer AgustaWestland since 1971 and mainly used in light transport, medevac, search-and-rescue and military roles.
Castle Air’s website says: “Nestled in the Cornish countryside you will find Castle Air’s facility, arguably one of the best in the country.
”Inside you will find numerous helicopters mainly Agusta 109s owned by Castle Air, and a dedicated team of engineers in attendance.”
The firm says it has been called upon to carry out an extremely wide variety of tasks, from filming in the Arctic Circle to VIP transport on the African equator.
It also buys and sells Agusta 109s from all around the world, with customer bases from Barbados to Australia.
A spokesman for the firm said a statement on Wednesday’s crash would be released later today.
She said: “We will be making a statement on our website later today.”
