UK authorities are investigating what they called a “serious incident” in the skies over London. According to the BBC, a business jet came close to a mid-air collision with a Turkish Airlines Boeing 777 heading to Heathrow. The Turkish plane, carrying 232 passengers, passed as close as 100 feet (30 metres) above, and half a mile away (0.8km) from the Citation 525 jet. Meanwhile, private jet pilot and PrivateFly’s CEO Adam Twidell has commented on the incident by highlighting jet safety. “Aviation safety – whether in a scheduled airliner or a private jet – is about a combination of modern, well maintained aircraft, and the experience and training of the pilot,” he explained. “Private jets are as safe, if not more so than travelling by scheduled airlines.” He said an updated version of the collision avoidance system, named TCAS, is currently in development to give clearer instructions.
