English: This photograph shows Apollo 1's Command Module a day after the fire that took the lives of astronauts Lt. Col. Virgil "Gus" Ivan Grissom, Lt. Col. Edward Higgins White II, and Lt. Cdr. Roger Bruce Chaffee. The photograph was taken in the White Room at Launch Complex 34. The exterior effects of the intense heat of the flash fire can be seen. An investigative board was promptly set up to examine the accident and identify the cause of the fire. The final report gave the results of the investigation as well as detailed suggestions for major design and engineering modifications, revisions to test planning, manufacturing procedures, and quality control. With these adjustments, the Apollo program became safer and successfully sent astronauts to the Moon.
