While at Lossie in the 80's an associate of mine on the nearby Nimrod line up the road recited an exploit of his :- While racing two Houchin's up the taxi-way on a weekend, one of them became detached from its rover
jacknifed
and flipped over several times!
The poor power set was righted and left outside GEF with a 731 one on it reading....... "turns over - won't start!"
I still larff over 20 years on!
P.S. I think WO GEF is still in orbit now
