What was the actual plane? Most can dump the fuel at approx 2 tons per minute, some cant. Just wondering why they decided to burn instead of dumping it. I am guessing you were on a Boeing 757? in that case they have no fuel dump facility but they are certified to land at near MTOW as are one or two Airbus aircraft, so weight is not an issue with certain aircraft.
Video shows a bird strike at Manchester on a 757 with a heavy fuel load but plane landed soon after with one engine that could burn any fuel and no fuel dump facility. Also note he was given notice that all runways were open for landing as soon as the mayday message was sent
