When the ride E-stops it does not return to the home position, it mearly lets gravity bring the ride to the lowest point, this also means that the gondola is not parallel to the ground but rather angled facing downward. In the event that the ride is unable to be homed such as a lack of air pressure, the ride will be Locked Out, a very large jack is placed under the front of the gondola then jacked up so as to level the gondola, then a roling stair case is wheeled to the front right corner of the gondola. Operators stand at the opposite end and corners to keep guests from walking off the edge. Once all of this is done, an air compressor is wheeled behind the ride and connected to a valve near the back row exit side corner. This allows the manual opening of restraints using the controls at on the side of that valve/box. Restraints are opened half a row at a time starting with the front row entrance side, then front row exit side, then middle row entrance side, etc. The rest of the evacuation procedures are the same, the ops will take your name, seat number, and ask if you're feeling alright.
I've had to do this many times^
thanks for explaining that
