The helicopter which crashed into a crane in central London this morning [Wednesday] was registered to Cornish company, Castle Air.
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 it also specialises 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, who are based in Yeovil.
