This is one of two shuttle launchpads at Canaveral.   The disaster was caused by management malfeasance (not mere misfeasance). The specifications called for the seven sections of each solid fuel booster to be sealed with two O-Rings. After engineers' warnings that if an O-Ring failed during freezing temperatures, it would be disastrous, NASA went ahead and changed the specifications to one O-ring being sufficient.   It had two, so what's the problem?   The launch in January 2006 goes ahead, kills seven people and when the Shuttle Prgram recommences, it calls for three O-Rings
