Two NASA T-38 jet trainer aircraft fly over the Space Shuttle Endeavour on Pad 39B at the Kennedy Space Center. After Atlantis leaves Pad A (out of frame), Endeavour will be moved from Pad B to Pad A to support the STS-127 mission. Currently, Endeavour is being prepared as a backup vehicle for Atlantis, and it will be designated STS-400 if in the unlikely event it’s needed for a rescue flight. The two pictured aircraft were piloted by Jack Nickel (in jet with tail number 62, top) and Charles Justiz (in jet with tail number 24). (NASA) #
