Now normally Michael Smiths article seem fairly technically accurate, but this is really really wide of the mark as far as i can see. Hot air pipes in the engines???
Maybe he is refering to air offtake pipes ? As for air offtake pipes being close to fuel pipes, name me one modern gas turbine engine with which this isn't the case. And as for Jimmy bloody Jones, where exactly are these hot air leaks in the wing tanks? Buffoon.
