Description of Driving Event:
On the STS 51/TOS mission, during payload deployment, commands intended to initiate only the primary SUPER*ZIP explosive cord actually resulted in the simultaneous firing of both the primary explosive cord and back-up explosive cord. This simultaneous explosive cord firing resulted in the rupture of a SUPER*ZIP containment tube and the release of contaminants and high energy debris into the orbiter cargo bay.
