Hi George

Thanks for your replies :-)

Its true you learn something new everyday. I feel quite educated about
fuel gauges now!

Well, if you run out in a plane, you do exactly the same thing. Only the road is
a few thousand feet below you. :-)

My point exactly! If you've got somewhere safe to land.

It reminds me of a comedy sketch, I think it was Dave Allen, when he's
talking about emergency set downs, into the side of a mountain, or
looking at the in flight safety card and someone drawn shark fins in
the water right by the exits.

Many thanks
