On 16 October 2007, NASA Managers completed the Flight Readiness Review, and held a press conference to announce the mission plan. The issue of the RCC panels raised by NESC was found to be of little immediate concern, because the NESC took pre-flight thermography data from "Endeavour" and compared it with "Discovery", but there was no commonality in flight history between the two vehicles. The research showed no significant difference between the panels prior to STS-114, and the panels today, which indicates the coating has not worsened during the previous flights, adding confidence that "Discovery's" RCC panels have had no deterioration in the flights since. NASA announced on the main shuttle page that "The Space Shuttle Program has determined that Discovery's astronauts can safely carry out their mission without having to replace the panels."
