In the years immediately after the Challenger disaster, several books were published describing the factors and causes of the accident and the subsequent investigation and changes. In 1987, Malcolm McConnell, a journalist and a witness of the disaster, published Challenger–A Major Malfunction: A True Story of Politics, Greed, and the Wrong ...
During the ascent phase, 73 seconds after liftoff, the vehicle experienced a catastrophic structural failure resulting in the loss of crew and vehicle. The Rogers Commission later determined the cause of the accident to have been the failure of the primary and secondary (backup) O-ring seals on Challenger ' s right Solid Rocket Booster (SRB ...
The commission found that the immediate cause of the Challenger accident was a failure in the O-rings sealing the aft field joint on the right solid rocket booster, causing pressurized hot gases and eventually flame to "blow by" the O-ring and contact the adjacent external tank, causing structural failure. The failure of the O-rings was ...

The mission ended in disaster following the destruction of Challenger 73 seconds after lift-off, because of the failure of an O-ring seals on Challenger ' s right solid rocket booster, which led to the rapid disintegration of the Space Shuttle stack from overwhelming aerodynamic pressures.
With Challenger, an O-ring that should not have eroded at all did erode on earlier shuttle launches. Yet managers felt that because it had previously eroded by no more than 30%, this was not a hazard as there was "a factor of three safety margin" (in reality, the part had failed, and there was no safety factor).
