IZ Reloaded writes "The Space Review has an interesting story written by Dwayne Day about the 1974 incident when astronauts onboard Skylab took photos of a facility that did not exist in the US called Area 51. From The Space Review: What the memo indicates is that there was a difference between the way the civilian agencies of the US government and the military agencies looked at their roles. NASA had ties to the military, but it was clearly a civilian agency. And although the reasons why NASA officials felt that the photo should be released are unknown, the most likely explanation is that NASA officials did not feel that the civilian agency should conceal any of its activities. Many of NASA's relations with other organizations and foreign governments were based on the assumption that NASA did not engage in spying and did not conceal its activities."
