The story says; " On Feb. 25, six days later, the same BA 747 flew 11 hours on three engines when an engine gave out on a flight from Singapore to London. However, in that case, the aircraft had been in flight several hours before the engine stopped functioning."
That's nice, but it completely contradicts what you said: "The next day that same plane flew to India on three engines." As I said, the facts in your quote are not true. India is not Singapore. The next day is not six days later. Outbound is not inbound.
