Re: BA 747 3 engine ferry PHX-LHR

Due to higher drag from having to fly at lower altirudes with three engines, they had to land at MAN. That is not true. Go read the report. Over the UK they had sufficient fuel to go and land at LHR, but the fuel was not in the right tanks. The B744 has a complex manually controlled fuel system, an...
