A launch pad fire during Apollo program tests at Cape Canaveral,
Florida, killed all three astronauts of Apollo 1 on this day in 1967. 
     
An investigation indicated that a faulty electrical wire inside the
Apollo 1 command module was the probable cause of the fire.

The astronauts, the first Americans to die in a spacecraft, had been participating in a simulation of the Apollo 1 launch scheduled for
the following month.
