Salute!

from scifi:

Maybe they thought if they switched off the electrics, they would also loose power to their trim switches.
If they thot that, then they were correct. Might be because using the wheel switches they could get nose up trim, ya think? The stab switches on the pedastal turn off electric power to the stab for all of the pseudo-manual functions. Then they have to crank that manual trim wheel ten turns just to get what HAL did in a half a second!!!
