fellows,
I somewhat disagree with the 'when gravity disappears a loop will result' theory.
To perform a loop there must be a rotating force about the lateral axis (such as
an 'up' elevator.
As it is, there is no rotating force. in S&L, all the forces are balanced.
So the result of the removal of gravity is an imbalance in the 4 forces.
The result would be a 'very' fast climb. (but no loop)
