+On January 28, 1986, the Space Shuttle Challenger broke apart 73 seconds into
+its flight, killing all seven crew members aboard. The spacecraft
+disintegrated 46,000 feet (14 km) above the Atlantic Ocean, off the coast of
+Cape Canaveral, Florida, at 11:39 a.m. EST (16:39 UTC). It was the first fatal
+accident involving an American spacecraft while in flight.
+
+The mission, designated STS-51-L, was the 10th flight for the orbiter and the
+25th flight of the Space Shuttle fleet. The crew was scheduled to deploy a
+communications satellite and study Halley's Comet while they were in orbit, in
+addition to taking schoolteacher Christa McAuliffe into space under the
+Teacher In Space program. The latter task resulted in a higher-than-usual
+media interest in and coverage of the mission; the launch and subsequent
+disaster were seen live in many schools across the United States.
+
+The cause of the disaster was the failure of the primary and secondary O-ring
+seals in a joint in the shuttle's right solid rocket booster (SRB). The
+record-low temperatures on the morning of the launch had stiffened the rubber
+O-rings, reducing their ability to seal the joints. Shortly after liftoff, the
+seals were breached, and hot pressurized gas from within the SRB leaked
+through the joint and burned through the aft attachment strut connecting it to
+the external propellant tank (ET), then into the tank itself. The collapse of
+the ET's internal structures and the rotation of the SRB that followed threw
+the shuttle stack, traveling at a speed of Mach 1.92, into a direction that
+allowed aerodynamic forces to tear the orbiter apart. Both SRBs detached from
+the now-destroyed ET and continued to fly uncontrollably until the range
+safety officer destroyed them.
+
+The crew compartment, human remains, and many other fragments from the shuttle
+were recovered from the ocean floor after a three-month search-and-recovery
+operation. The exact timing of the deaths of the crew is unknown, but several
+crew members are thought to have survived the initial breakup of the
+spacecraft. The orbiter had no escape system, and the impact of the crew
+compartment at terminal velocity with the ocean surface was too violent to be
+survivable.
+
+The disaster resulted in a 32-month hiatus in the Space Shuttle
+program. President Ronald Reagan created the Rogers Commission to investigate
+the accident. The commission criticized NASA's organizational culture and
+decision-making processes that had contributed to the accident. Test data
+since 1977 demonstrated a potentially catastrophic flaw in the SRBs' O-rings,
+but neither NASA nor SRB manufacturer Morton Thiokol had addressed this known
+defect. NASA managers also disregarded engineers' warnings about the dangers
+of launching in cold temperatures and did not report these technical concerns
+to their superiors.
+
+As a result of this disaster, NASA established the Office of Safety,
+Reliability, and Quality Assurance, and arranged for deployment of commercial
+satellites from expendable launch vehicles rather than from a crewed
+orbiter. To replace Challenger, the construction of a new Space Shuttle
+orbiter, Endeavour, was approved in 1987, and the new orbiter first flew in
+1992. Subsequent missions were launched with redesigned SRBs and their crews
+wore pressurized suits during ascent and reentry.
