STS-5 launched from Kennedy Space Center, Florida, on November 11, 1982. This was the first operational flight of the Space Shuttle "Columbia" and became known as the "We Deliver" mission. Two commercial communications satellites with Payload Assist Module upper stages (PAM-D) were successfully deployed from the Orbiter's cargo bay, a new first. This activity was shared with the world when the onboard television tape was played to the control center later that evening. In addition to collecting precise data to document the Shuttle's performance during launch, boost, orbit, atmospheric entry and landing phases, STS-5 carried a Getaway Special experiment, three Student Involvement Project experiments, and medical experiments. STS-5 was the last flight to carry the Development Flight Instrumentation (DFI) package to support flight testing.
