P3L-997

P3L-997 is a planet on which there was a huge flood rising and SGC sent a team together with Daniel Jackson to help relocate the people. When SGC sent the virus Avenger to P5S-117 which was modified by Baal's scientists and sent it to every other stargate in the galaxy, the team on this planet was one of twelve teams that didn't make it back to Earth in the first run before the whole Stargate network was taken down. They were, though, later recovered. (SG1: "Avenger 2.0")
