In short
On January 27, 1967, a cabin fire killed astronauts Gus Grissom, Ed White, and Roger Chaffee during a launch rehearsal test at Cape Kennedy, exposing critical safety flaws in the Apollo spacecraft design. The disaster halted the lunar program for 21 months while NASA overhauled procedures and hardware, ultimately shaping how the agency would send humans to the Moon.
How it unfolded.
The five-minute version
What actually happened.
The Apollo program, also known as Project Apollo, was the United States human spaceflight program led by NASA, which landed the first humans on the Moon in 1969. Apollo was conceived in 1960 in the Dwight D. Eisenhower presidency during Project Mercury and executed after Project Gemini. Apollo was later dedicated to President John F. Kennedy's national goal, "before this decade is out, of landing a man on the Moon and returning him safely to the Earth" in his address to the U.S. Congress on May 25, 1961.

Fire erupts during test
At 6:31 PM EST, an electrical arc ignited in the Command Module cabin during the plugs-out test. The 100% oxygen environment caused the fire to spread rapidly. All three crew members—Grissom, White, and Chaffee—were overcome within seconds. Recovery teams could not open the hatch in time.
