I just hope this doesnít kill the manned spaceflight program or the ISS with it. This is likely to be the death knell of the shuttle program. They need at least four shuttles to keep the program going. That coupled and that this may very well have been brought on by stress over the years on Columbia. Hopefully they can dump enough money into the Russian space program to keep the ISS going with Soyuz. It is a time to mourn but also a time to keep in mind that the best way to honor them would be to return to space as soon as possible.
I donít think it could have been a terrorist attack. Youíre not going to sneak in a missile that can hit a shuttle at that speed and attitude or crash and aircraft into one. She was at 200,000 feet over Texas at 12,500 mph when she was coming in over Texas. The only way I can think of is the outside of someone on the inside of NASA tampering with the programming. Youíre dealing with a highly outside chanceÖ
