Challenger Disaster

At 11:38 am January 28, 1986, NASA's Flight 51-L was done due to the Challenger's disaster and the 25th Space Shuttle took off. This is the mission of "space teacher". When lift off, the ground temperature is 36 degrees Fahrenheit, which is 15 degrees Fahrenheit lower than the temperature NASA issued earlier. This is the 10th flight of the challenger. Take-off was postponed several times. The last bus departed. After 35 seconds of takeoff, the space shuttle climbed high in the sky and was hit by a strong wind.

After the space shuttle disaster by the Challenger in 1986, Go Fieber appeared again. Allan McDonald, the contractor's engineer Morton Thiokol, is concerned about freezing the challenger's temperature in Florida on the day of the launch, in his book "Truth, Liars, and O-Ring: Space Shuttle Challenger Disaster" And it explains. Due to the lack of tests, McDonald had a video conference before the start of the recommended delay, was challenged each time the recommendation was postponed and McDonald was asked to prove that the start fails with a challenge. Because he does not have data on the low temperature test that supports his claim

In 2009, former director of the Morton - Thiocolspace shuttle solid state rocket project Alan MacDonald published his book "Truth, Lies and O - Ring: Space Shuttle Challenger Disaster Insider". So far, no one has participated directly in the decision to launch a challenger and never published memoirs on that experience. In December 2013, Beyonce first announced a song called "XO", a former public relations officer at NASA Steve Nasbit, after the disaster: "The flight controller is here." "This song was controversial, former NASA astronauts and families labeled Knowles' samples" insensitive ". Hadeep Phil at New York Post explained the existence of this sample as "incenseless" and Keith Cowing at NASA Watch suggested using clip ranges. From "negligence" to "hatred"
