"Challenger: The Final Flight" on Netflix

The new 4-part TV documentary TV mini-series "Challenger: The Final Flight", created by Steven Leckart, and Glen Zipper streams September 16, 2020 on Netflix:

The crew consisted of five 'NASA' astronauts, and two payload specialists. The mission carried the designation 'STS-51-L' and was the tenth flight for the 'Challenger' orbiter.

"The spacecraft disintegrated over the Atlantic Ocean, off the coast of Cape Canaveral, Florida, at 11:39 a.m. EST (16:39 UTC). The disintegration of the vehicle began after a joint in its right solid rocket booster ('SRB') failed at liftoff. The failure was caused by the failure of 'O-ring' seals used in the joint that were not designed to handle the unusually cold conditions that existed at this launch. 

"The seals' failure caused a breach in the SRB joint, allowing pressurized burning gas from within the solid rocket motor to reach the outside and impinge upon the adjacent SRB aft field joint attachment hardware and external fuel tank. This led to the separation of the right-hand SRB's aft field joint attachment and the structural failure of the external tank. Aerodynamic forces broke up the orbiter..."
