Lessons Learned - Emergency Stop (E-STOP) Switch Cover; Inadvertent Disconnection of Flex Hoses; Orbiter Tow Tug and Support Truck Emergency Stop
Year: 1992
Abstract: Description of Driving Event:
After the towing convoy turned off the runway onto the tow way, the cool tractor/trailer suddenly stopped. The observer caused the rig to suddenly stop when his hand inadvertently came in contact with the E-STOP switch cover. This caused the boom to oscillate up and down. The boom operator lowered the boom to get maximum extension on the two coolant flex hoses attached to the orbiter. The boom's oscillation caused the flex hoses to be whipped loose before the orbiter could stop. The flex hoses fell to the ground with freon 14 spewing from them.
