Aviation expert Alex Macheras insists potential terrorist involvement in the crash of EgyptAir flight MS804 will raise wider concerns about UK airport security.
The plane vanished from radar early this morning during an overnight flight from Paris to Cairo, roughly 20 minutes before it was due to land. There were a total of 66 people on board.
French President Francois Hollande has now confirmed all information points towards a crash in the Mediterranean Sea and "no hypothesis" about the cause of it could be ruled out. A major search and rescue operation by Greek and Egyptian armed forces is ongoing.
Macheras pointed out the implications of what it would mean for the UK if the incident is ruled to be the work of terrorists.
He told Julia Hartley-Brewer: "If this turns out to be a case of terrorism, the spotlight shifts much closer to home. You have to ask how on earth was a terror attack carried out on an aircraft which left an international superhub like Charles De Gaulle airport with security as strong as ours at Heathrow?"
Macheras said the model of flight MS804, an Airbus A320, is a widely-used type of plane with a good safety record.
"If you've ever flown short-haul in your life, I guarantee you've more than likely been on an Airbus A320," he added. "They're all very young with the latest technology.
"For this to be involved in this tragic incident draws many questions, but the biggest one is whether terrorism was involved in this morning's crash."
