NASA satellite falls over in lab when bolts removed

A very expensive accident happened to a satellite when it was being repositioned and fell off its stand. Basically, the team responsible for it had bolted it down, some other team came and 'borrowed' their bolts without asking. First team didn't re-check the bolts because they assumed they were still there.

... Quote:
As the NOAA-N Prime spacecraft was being repositioned from vertical to horizontal on the "turn over cart" at approximately 7:15 PDT today, it slipped off the fixture, causing severe damage. (See attached photo). The 18' long spacecraft was about 3' off the ground when it fell.

The mishap was caused because 24 bolts were missing from a fixture in the “turn over cart”.

Two errors occurred. First, technicians from another satellite program that uses the same type of “turn over cart” removed the 24 bolts from the NOAA cart on September 4 without proper documentation.

Second, the NOAA team working today failed to follow the procedure to verify the configuration of the NOAA “turn over cart” since they had used it a few days earlier.

The shock and vibration of the fall undoubtedly caused tremendous damage. Significant rework and retest will be required.
