With uncanny accompaniment to the Concorde disaster of July 25, problems affected no less than three separate British Airways Concorde flights over the following weekend.

The BBC reports that on Sunday evening (July 30th), BA Concorde Flight 003 bound for New York was diverted to Gander in Newfoundland in Canada after passengers reported a smell of fuel at the back of the cabin. Just to be cautious the crew decided to divert the plane. The passengers were later flown onto New York in a chartered Boeing 737.
Earlier on the same day, a Concorde was grounded at Heathrow due to refuelling problems, and 51 passengers on the 10.30 flight from Heathrow to New York were transferred to a standby aircraft.
It has also emerged that late on Saturday evening, a BA Concorde flight from New York was met by emergency services on the ground at Heathrow, after the pilot was alerted to a large bang inside one of the engines. A mixture of fuel and air in the engine was blamed for the noise, which was similar to a car backfiring, and was no more serious than that. Guess the passengers got somewhat spooked.
British Airways evidently described the action taken for all three of its troubled Concordes as ‘routine safety procedures’.


Also called ‘reheat’, the afterburner is a second combustion chamber in a turbojet or turbofan engine, immediately in front of the engine’s exhaust nozzle. The injection and combustion of extra fuel in this chamber provide additional thrust for takeoff or supersonic flight. In most cases the afterburner can nearly double the thrust of a turbojet engine. Since the jet nozzle must be larger when using the afterburner, an automatic, adjustable nozzle is an essential component of the afterburner system. Because the afterburner sharply increases fuel consumption and is generally less effective at subsonic speeds, its use is for the most part restricted to supersonic military aircraft.
