A British tourist has claimed that an emergency exit door on an Emirates Airline A380 aircraft blew open at 27,000ft.
David Reid said in comments published by the UK's Mail newspaper that there was a "massive explosion" two hours into the flight.
Reid, travelling with his son Lewis, said freezing air rushed into the cabin after the door in business class came an inch and a half ajar.
The newspaper reported that the drama happened on Monday as the two Britons flew from Bangkok to Hong Kong.
An Emirates spokesman told the paper: "We can confirm there was a whistling noise emanating from one of the doors on the A380 upper deck on flight EK384 between Bangkok and Hong Kong on Monday, February 11. At no point was the safety of the flight in jeopardy."
But Reid said: "We were about two hours in when suddenly there was a huge blast. It was a real shock, so loud that I thought a bomb might have gone off. Air was gushing into the cabin like a gale.
"It was complete panic. The emergency door was ajar and leaving a gaping hole. You could see straight out into the atmosphere, 27,000ft up."
Reid, who has a private pilot’s licence, said cabin crew started grabbing blankets and pillows which they stuck together with duct tape to fill the gap.
"The conditions were terrible for the rest of the flight. The door continued to make a horrendously loud droning sound which made it impossible to speak to each other. Worst of all, it was absolutely freezing."
The paper added that the incident was reported to the Department of Transport’s Air Accidents Investigation Branch who have passed it on to air investigators at the UAE General Authority for Civil Aviation.
