Space Shuttle Flight 20 (STS-51I) Post Flight Presentation 

Thanks for these videos; keep them coming. While I was in the front room of Mission Control at the time, this is the first time that I've seen the bent PAM sunshield. That was a potentially serious situation. Had they not been able to move the sunshield off the satellite, they wouldn't have been able to deploy the satellite. It might also have required an EVA to move the sunshield so that the payload bay doors could close. Note the comment about the automatic features of the arm failing so that they had to move one joint at a time. That was a show of great skill.
