Hang on a minute!!!!!!!!!!!!!!!!!!! Quite a lot of cars were permanently
immersed in water up to their axles at the Honeybourne transit park in days
of yore. Was this to prove:
1. +ve was better than -ve or vice versa?
2. The quality of paint would fight off corrosion before the warranty ticket
was signed at customer handover, or
3. The drains on the WW2 airfield really were as bloody useless as everyone
said they were?
