Well Done Airline Tycoon for some factual info on the B777 returning into Heathrow last night.
Just a few more points.
the aircraft was seen to get airborne with smoke from the location of the left main gear. This which was darker then the normal fuel colour when associated with venting. This was visible for about 10 to 15 mins as the aircraft flew south.
A runway inspection confirmed the extreme smell of fuel although no residue fuel was present on the surface apart from at SB1 where the aircraft was waiting prior to departure.
Reports were arriving all the time , not only from staff and flight crews at Heathrow but members of the public and although the flight crew initially had no abnormal indications BA were concerned enough to return the aircraft. After a short amount of time dumping fuel the aircraft returned on a Full emergency. A small amount of smoke was seen from the left main gear on vacating the runway but this was down to fuel contamination of the brakes.
Once on stand the undercarriage doors were lowered and the left side was totally smothered in fuel. Further investigations were taking place as initially the leak could not be found.
Intersting point of note . What would have happened if this had been in darkness ?? There would have not been any visible sightings from the ground !!!
