solid rocket explosion
The last statement captured by the crew cabin recorder came just half a second after this acceleration, when Pilot At T+73.124, the aft dome of the liquid hydrogen tank failed, producing a propulsive force that rammed the hydrogen tank into the LOX tank in the forward part of the ET.
Solid rocket motors can present a handling risk on the ground, as a fully fueled booster carries a risk of accidental ignition. Three of the crew members, A separate related accident occurred at the Pacific Engineering and Production Company of Nevada (PEPCON) plant in In the aftermath of the accident, NASA was criticized for its lack of openness with the press.

Mulloy said, "My God, Thiokol, when do you want me to launch—next April? We never changed a mission rule on the fly.
We are looking at checking with the recovery forces to see what can be done at this point. Several engineers (most notably Allan McDonald, Ebeling and Thiokol management initially supported its engineers' recommendation to postpone the launch, but NASA staff opposed a delay. The flight director confirms that.

While some shallow-water recovery efforts continued, this was unconnected with the accident investigation; it aimed to recover debris for use in NASA's studies of the properties of materials used in spacecraft and launch vehicles.A soccer ball from the personal effects locker of Mission Specialist Ellison Onizuka was also recovered intact from the wreckage, and was later flown to the The remains of the crew that were identifiable were returned to their families on April 29, 1986. The solid rocket motor boost stage for the payload had not ignited either and was quickly ruled out as a cause of the accident. The test included filling the oxidizer tank with 4,500 kg (9,900 lb) of nitrous oxide, followed by a 15-second cold flow injector test. George Martin, formerly of The unrealistically optimistic launch schedule pursued by NASA had been criticized by the Rogers Commission as a possible contributing cause to the accident. The event made headlines in newspapers worldwide.Tufte has also argued that poor presentation of information may have also affected NASA decisions during the last flight of the space shuttle I want to say something to the schoolchildren of America who were watching the live coverage of the shuttle's takeoff.
