- Orbiting Solar Observatory: (OSO B)
1964: Orbiting Solar Observatory: OSO B suffered an incident during integration and checkout activities on 14 April 1964. The satellite was inside the Spin Test Facility at Cape Canaveral attached to the third stage of its Delta C booster when a technician accidentally ignited the booster through static electricity. The third-stage motor activated, launched itself and the satellite into the roof, and ricocheted into a corner of the facility until burning out. Three technicians were burned to death.
