On January 27, 1967, a fire in the Apollo 1 Command Module killed astronauts Gus Grissom, Ed White and Roger B. Chaffee during a launch rehearsal. From the article:
"Apollo 1: The Fatal Fire,
The Apollo program changed forever on Jan. 27, 1967, when a flash fire swept through the Apollo 1 command module during a launch rehearsal test. The three men inside perished despite the best efforts of the ground crew. It would take more than 18 months, and extensive redesigns, before NASA sent more men into space.
NASA had a lofty goal, set by President John F. Kennedy in 1961, to land a man on the moon and return him safely to Earth by the end of the decade. Earlier Mercury and Gemini flights had been the first steps toward that goal, testing how humans behaved in space and how to do technical spacecraft procedures such as rendezvous. Now the Apollo missions would take astronauts all the way to the moon for orbital missions and landing missions. The first manned mission — an Earth-orbiting mission — was originally designated Apollo Saturn-204, or AS-204, but was later renamed Apollo 1.
The Apollo 1 fire was a difficult time for NASA and its astronauts, but the improvements in astronaut safety allowed the agency to complete the rest of the program with no further fatalities. The agency also met Kennedy's goal of landing a man on the moon in 1969, during Apollo 11.
NASA had a special ceremony honoring the Apollo 1 astronauts on the 50th anniversary of their deaths in 2017, which included unveiling a new exhibit at the Kennedy Space Center showing the hatches of the damaged command module.
The astronauts
The Apollo 1 crew commander, Virgil "Gus" Grissom, was an Air Force veteran of the Korean War. He was chosen was among NASA's first group of seven astronauts, the Mercury Seven. Grissom was America's second person in space in 1961. On that mission, Mercury's Liberty Bell 7, the hatch door blew for unknown reasons upon splashdown. Grissom ended up in the water and was rescued by a helicopter (which at first tried, in vain, to pick up the spacecraft; the spacecraft was later pulled from the ocean floor in 1999).
Some in the Astronaut Office were skeptical that Grissom's reputation would recover (many believed Grissom blew the hatch; he swore he didn't). However, Grissom successfully commanded the first Gemini flight, Gemini 3, and was selected to do the same for Apollo.
Fellow spaceflight veteran Ed White, an Air Force lieutenant colonel, was the first American to make a spacewalk, on Gemini 4 in 1965. The images of him soaring in space for 23 minutes are still frequently seen today; it is considered one of history's most memorable spacewalks.
Roger Chaffee was a seasoned Navy lieutenant commander who joined the program in 1963. Although a rookie in space, he had spent years supporting the Gemini program, most publicly as CapCom on Gemini 4. Now getting a chance to fly after five years in the program, he said, "I think it will be a lot of fun."
Every astronaut in the Apollo program had flight experience, and many were test pilots. They were used to seeing machines under development and dealing with delays, and assessing the airplanes' readiness for flight. In the view of many of these astronauts, the Apollo command module just wasn't ready yet. Engineering changes were still in progress as NASA prepared for the countdown test.
On his last visit home in Texas, Jan. 22, 1967, Grissom grabbed a lemon off a citrus tree in the backyard. His wife, Betty, asked what he was going to do with it. "I'm going to hang it on that spacecraft," he answered as he kissed her goodbye. He hung it on the flight simulator after he arrived at the Cape.
The morning of the test, the crew suited up and detected a foul odor in the breathing oxygen, which took about an hour to fix. Then the communications system acted up. Shouting through the noise, Grissom vented: "How are we going to get to the moon if we can't talk between two or three buildings?"
With communications problems dragging on, the practice countdown was held. Then at 6:31 p.m. came a frightening word from the spacecraft: "Fire."
Deke Slayton, who oversaw crew selections at NASA and was present for the test, could see white flames in a closed-circuit television monitor pointing toward the spacecraft. The crew struggled to get out. Technicians raced to the scene, trying to fight the fire with extinguishers amid faulty breathing masks. [Video: Apollo 1 Remembered – Report from the Archives]
At last, the door was open, but it was too late.
The aftermath and changes
A NASA review board found a stray spark (probably from damaged wires near Grissom's couch) started the fire in the pure oxygen environment. Fed by flammable features such as nylon netting and foam pads, the blaze quickly spread. [Infographic: How the Apollo 1 Fire Happened]
Further, the hatch door — intended to keep the astronauts and the atmosphere securely inside the spacecraft — turned out to be too tough to open under the unfortunate circumstances. The astronauts had struggled in vain to open the door during the fire, but the pressure inside the spacecraft sealed the door and made it impossible to open.
NASA administrators sit at the witness table before the Senate Committee on Aeronautical and Space Services, chaired by Senator Clinton P. Anderson, on the Apollo 1 (Apollo 204) accident. The individuals are (L to R) Dr. Robert C. Seamans, NASA Deputy Administrator; James E. Webb, NASA Administrator; Dr. George E. Mueller, Associate Administrator for Manned Space Flight, and Maj. Gen. Samuel C. Phillips, Apollo Program Director.

The board listed a damning set of circumstances, failures and recommendations for future spacecraft designers to consider.
The U.S. Senate conducted its own investigation and hearings and published recommendations of its own, while saying NASA's failure to report its problems with Apollo "was an unquestionably serious dereliction."
Decades later, NASA recalls the Apollo 1 incident every January in an annual Day of Remembrance. It also honors the Challenger and Columbia crews, who died in 1986 and 2003, respectively.
