Video highlights from Challenger Disaster: Lost Tapes. For starters, there was no explosion. A cloud of vapour engulfs the space shuttle Challenger in a picture taken on the morning of January 28, The disaster claimed the lives of all seven astronauts on board, including high school teacher Christa McAuliffe, and brought NASA's human spaceflight program to an abrupt but temporary halt. Now, over 30 years on from the tragedy, the story of what exactly happened to Challenger remains clouded by faulty memories and misinformation.

I was working data communications. Everything was green on my board, the shuttle launched, and a few seconds later everything went to hell. I stared at my controls, tried to get things to reconnect, and then I finallly looked up at the TV display. Throughout schools, kids from kindergartners to high school students were ready to watch Sharon Christa McAuliffe, the first teacher in space, launch into orbit. Instead they saw a tragedy.

The space shuttle was engulfed in a cloud of fire just 73 seconds after liftoff, at an altitude of some 46, feet 14, meters. It looked like an explosion, the media called it an explosion and even NASA officials mistakenly described it that way initially. But later investigation showed that in fact, there was no detonation or explosion in the way we commonly understand the concept. The fuel tank itself collapsed and tore apart, and the resulting flood of liquid oxygen and hydrogen created the huge fireball believed by many to be an explosion. After the collapse of its fuel tank, the Challenger itself remained momentarily intact, and actually continued moving upwards.

And they were equally horrified to learn in the aftermath of the disaster that the faulty design had been chosen by NASA to satisfy powerful politicians who had demanded the mission be launched, even under unsafe conditions. Meanwhile, a major factor in the disaster was that NASA had been ordered to use a weaker sealant for environmental reasons. Finally, NASA consoled itself and the nation with the realization that all frontiers are dangerous and to a certain extent, such a disaster should be accepted as inevitable. At least, that seems to be how many people remember it, in whole or in part. But spaceflight historians believe that each element of the opening paragraph is factually untrue or at best extremely dubious. They are myths, undeserving of popular belief and unworthy of being repeated at every anniversary of the disaster. The flight, and the lost crew members, deserve proper recognition and authentic commemoration.

All seven crew members were killed. It was the 25th flight of a Space Shuttle. The cause of the explosion was a part called an O-ring that broke in the right solid rocket booster. During the flight, hot gases escaped from the O-ring and made it break apart. It was very cold on the morning of the Space shuttle's launch. They were later proved wrong. Another problem was that the temperature was so low that icicles were hanging from some parts of the launch pad.
