Columbia exploded while coming down to land today, killing all seven astronauts on board and leaving wreckage over Nacogdoches, Texas.
I still remember clearly when the Challenger exploded during take off back in 1986. It was the first national tragedy that I can remember clearly, I was in middle school and we all just watched the news in disbelief. My condolences go out to the families and friends of the astronauts and everyone else involved in the shuttle program.
It can even be seen on radar...
