NASA Space Shuttle Challenger Explosion Disaster - 73 Seconds Into Flight January 28 1986

http://AviationExplorer.com - The Space Shuttle Challenger disaster occurred on January 28, 1986, when Space Shuttle Challenger broke apart 73 seconds into its flight, leading to the deaths of its seven crew members. The spacecraft disintegrated over the Atlantic Ocean, off the coast of central Florida at 11:38 am EST. Disintegration of the entire vehicle began after an O-ring seal in its right solid rocket booster (SRB) failed at liftoff. The O-ring failure caused a breach in the SRB joint it sealed, allowing pressurized hot gas from within the solid rocket motor to reach the outside and impinge upon the adjacent SRB attachment hardware and external fuel tank. This led to the separation of the right-hand SRB's aft attachment and the structural failure of the external tank. Aerodynamic forces promptly broke up the orbiter.

The crew compartment and many other vehicle fragments were eventually recovered from the ocean floor after a lengthy search and recovery operation. Although the exact timing of the death of the crew is unknown, several crew members are known to have survived the initial breakup of the spacecraft. However, the shuttle had no escape system and the astronauts did not survive the impact of the crew compartment with the ocean surface.

There was nothing wrong with the "O-ring seals", there was nothing wrong with the solid boosters. The Challenger was destroyed as a result of a leak in the external fuel tank. A crack developed between the oxygen and hydrogen fuel tanks, hydrogen, and probably oxygen, leaked out, ran back along the outside of the external tank almost to the end, where it ignited. The flame propagated forward until it reached the crack causing a tremendous explosion which destroyed the Challenger.

@eddsworldfan333 he said obviously. You can't give him crap about being obvious when he precedes it with 'obviously'. He is being professional.

I dont think he was being unprofessional about announcing this sort of thing. what was he supposed to say? ''HOLY SHIT GODDAMIT"? really? that would have been horribly wrong and im sure people in the control room were freaking out but they still had to do their jobs
