Last-minute modifications to the satellite's tether-reel assembly included the addition of a quarter-inchdiameter securing bolt, which apparently jammed the mechanism inflight, a board of international investigators reported last week.
The board's preliminary analysis indicates that this bolt prevented the free movement of a device called the level wind mechanism, which feeds out tether tether

Although shuttle astronauts managed to clear both snags SNAGS,

Investigators continue to examine all of the major problems encountered during the mission, including an initial failure to deploy the satellite and the final tether snag, which developed at the far end of the deployment boom.
