When they have their open house in May, they usually give tours. To see an M1A1
tank climb up the max grade is something else!
All the vehicles have to climb 1/2 way up the grade and be shut off with the
parking brake holding the vehicle. The vehicle is then checked for leaks. Then
it is restarted and a 'hill start' is performed. This must be quite a trick in
a Jeep to not go over backwards!
There is a large steel plate at the top of the hill over which a cable is
placed. The cable is tied to the vehicle under test and to another vehicle of
equal weight on the other side of the hill in case something goes wrong during
the test...
