BRITISH Airways has banned cabin crew from microwaving their own food after a curry exploded at 10,668m, causing around $48,000 of damage to an aircraft.

A fire extinguisher was used to tackle the blaze on April 30 on a Heathrow to Miami flight, when the high-powered microwave ignited a ready meal that a stewardess had bought from a supermarket.

“The fire lasted only a couple of seconds,” said a BA spokesman.

“As a precaution a specialist extinguisher was used in the microwave.

“However, at no time was there any danger to passengers or the aircraft.”
