![]() ' I strongly opposed the launch, expecting that the elasticity of the O-ring would definitely be lost if the SBR cooled down the night before the launch.īelow is a photo of the launch pad taken early in the morning of the launch day. I can't say that it has enough elasticity to maintain its sexuality. That led to the aerial disassembly of the Challenger.Ī team of engineers, including McDonald, who was the chief engineer of the rocket manufacturer Morton-Siocol (now ATK Ranch Systems ), who was in charge of designing and manufacturing the SRB, said, 'O-rings are airtight when the temperature is below 12 ° C. As a result, high-pressure and high-temperature gas leaked from the SRB immediately after launch, causing structural collapse in various places. Subsequent analysis revealed that the direct cause of the accident was ' damaged O-rings on the Solid Rocket (SRB) mounted on the Space Shuttle.' The O-ring to prevent fuel leakage lost its elasticity and was damaged, and the airtightness was impaired. Space shuttle Challenger exploding during launch -YouTube You can see the moment of the Challenger's aerial disassembly, which attracted a lot of attention as a major accident that shakes the United States, from the following movie. Launched from the Kennedy Space Center in Florida on January 28, 1986, the Challenger disassembled in the air 78 seconds after launch. ![]() I was 83 years old.Īllan McDonald, Who Refused To Approve Shuttle Challenger Launch, Dead At 83: NPR ' Alan McDonald, an engineer who accused him of 'forcing a launch,' died on Mafrom a fall-induced brain contusion. In 1986, the Space Shuttle Challenger was disassembled in the air immediately after its launch, killing all seven crew members in the ' Challenger Explosion Accident. 09:00:00 Alan MacDonald, an engineer who accused NASA of concealment in the Challenger explosion, died
