What was the main cause of the Challenger explosion?
Hot gases from the rocket had slipped past the O-rings in two of the SRB segments. At roughly the 73-second mark after launch, the right SRB triggered the rupture of the external fuel tank. Liquid hydrogen and oxygen ignited, and the explosion enveloped Challenger.

What happened to the Challenger crew bodies?
In March 1986, the remains of the astronauts were found in the debris of the crew cabin. Though all of the important pieces of the shuttle were retrieved by the time NASA closed its Challenger investigation in 1986, most of the spacecraft remained in the Atlantic Ocean.
Did the families of the Challenger crew sue NASA?
After the 1986 Challenger disaster, four families of the seven astronauts killed reached out-of-court settlements with the Justice Department for a total of $7.7 million. The wife of Challenger pilot Michael Smith sued NASA in 1987.
Did they find any body parts from the Challenger?
The National Aeronautics and Space Administration said today that it had recovered remains of each of the seven Challenger astronauts and had finished its operations to retrieve the wreckage of the space shuttle’s crew compartment from the ocean floor.
Did anyone get charged for the Challenger disaster?
The Rogers Commission Report was created by a Presidential Commission charged with investigating the Space Shuttle Challenger disaster during its 10th mission, STS-51-L.
What were the last words of the Challenger crew?
Previously, the last known words from the Challenger were those heard from Commander Dick Scobee to ground controllers, when he responded ″Roger, go at throttle up,″ confirming that the shuttle’s main engines had been raised to full power.
Did they ever find the bodies of the Challenger crew?
What was the condition of the Challenger crew bodies?

What caused the Challenger accident?
The commission found that the Challenger accident was caused by 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.
Why is the Challenger exploded?
Their investigation revealed that the O-ring seal on Challenger’s solid rocket booster, which had become brittle in the cold temperatures, failed. Flames then broke out of the booster and damaged the external fuel tank, causing the spacecraft to explode and disintegrate.
