If you are 40 years or older, you may remember January 28th 1986. It was the day of a huge NASA catastrophe off the coast of Cape Canaveral, Florida, where at 11:38 am EST, 73 seconds after take-off, Space Shuttle Challenger exploded in a tremendous burst over the Atlantic. Now, for a second time this matter leaves the world breathless. Though, this latest shock even surpasses the one of 30 years ago. At least six of the seven Challenger crew members are said to be still alive; four of them even under the same name.
