Kennedy Space Center and Cape Canaveral have seen more than their share of disasters. A launch catastrophe is unmistakable—tremendous noise, a horrendous fireball, and smoking debris falling into the ocean. My mind flashed back to the frigid morning of January 28, 1986. I had been standing outside and seen Challenger lift off from pad 39B, only to disappear into a violent conflagration shortly afterward. I remember expecting—hoping—that Challenger would emerge from the fireball, fly around, and land behind me at the Shuttle Landing Facility. But we never saw Challenger again. I recalled leaving the site with a few friends as debris and smoke trails continued to rain down into the Atlantic, just off the coast. It was a terrible thing to witness.
