I was catching up on my backlog of magazines at the weekend, and in
one of them was a short news piece about a 747 that was getting wheeled
out of BA's Cardiff maintenance facility, when someone inadvertently
retracted the undercarriage.  The result was $1million repair charge.

I am rather amazed that this is possible, given that there are all sorts
of interlocks between the undercarriage and other aircraft systems.

Does anyone know more about this incident in particular, and this kind
of scenario in general.
