Extraordinary, Tony.

I also believe that it was designed to leak like a seive when when it was on
the ground and constantly stood in a pool of its own fuel which ran from its
wing tanks. The gaps sealed once it was in the air and the metal expanded
from the heat.

They had to detach the towbar from the tractor when they pulled it out onto
the runway. If they'd left it attached, even starting one engine and
bringing it to idle speed would have bent the towbar like a strand of wet
spaghetti. For the same reason it couldn't use its brakes once the engines
were started.

I wonder what they've replaced it with?  :-)
