COSPAR: F800715A. Defense Meteorological Satellite Program. Although there was a press release immediately after the launch (by the spacecraft SPO) that said the 2nd stage motor exploded, in reality the problem was found to be due to poor design of the electrical connectors between the 2nd and third stages and a separation problem that ripped the wiring out of the spacecraft.
