Columbia

It was only few days ago that I posted a video of the Challenger disaster. Today is the 4th anniversary of the Columbia shuttle disaster, which was destroyed as it was entering the Earth's atmosphere, on return from a successful mission. Little needs to be added to what was said for the Challenger crew, but at least the men and women of the Columbia shuttle had the opportunity to go into space (an experience very few humans have had). Better to go and see, than to die before you've even left the planet.
