87. Virgil Ivan "Gus" Grissom was a U.S. Air Force pilot, a NASA astronaut, and the second American to fly into space. What caused Grissom's death on January 27, 1967?
From Quiz They Went That-A-Way Part II
Answer:
space capsule training accident
Grissom was killed along with fellow astronauts Ed White and Roger B. Chaffee, when a flash fire raced through their Apollo One space capsule as it sat atop the booster vehicle, on the launch pad at Cape Kennedy.
In an official report, NASA announced the fire was the result of a short circuit, accelerated by a pure oxygen artificial environment inside the space capsule.
Grissom was a veteran of two previous space missions. At the conclusion of his first space flight (Mercury-Redstone 4), on July 21, 1961, which lasted about 15 minutes, Grissom was criticized for what was first thought to be an action he committed that resulted in the loss of his space capsule. While being picked up following a successful flight and splashdown in the Atlantic Ocean, the hatch door release explosives of his "Liberty Bell 7" space capsule prematurely detonated, and opened, resulting in the capsule filling up with water and sinking some 16,000 feet to the ocean floor. Grissom was rescued by his helicopter recovery team, but the capsule, loaded with vital data was lost. Some speculated at the time that during the recovery operation, Grissom either panicked, or accidentally activated hatch releasing explosives too soon.
Grissom became the first astronaut to return to space, serving as the command pilot aboard the "Gemini 3" space mission, with Astronaut John W. Young in March of 1965.
Ed White was the first American astronaut to perform a "spacewalk" (EVA) in June of 1965, aboard the "Gemini 4" space mission, flown with astronaut James McDivitt.
The Apollo 1 mission would have been the first space flight for Astronaut Roger B. Chaffee.
Grissom's Liberty Bell 7 space capsule was located and recovered 38 years after it sank, in 1999.
