Grissom's son Mark told The Washington Post in 2017 that his father had concerns about the Apollo spacecraft before the fire, and he made them known prior to his death. "I was kind of expecting him not to go," Mark told the outlet. "But he was doing everything he could to get the thing ready to go into space. He wasn't having much luck." Although multiple investigations took place following the first fatal accident in the history of the U.S. space program, it was ultimately concluded that design flaws and a difficult-to-open hatch door led to Grissom's death, according to The New York Times. He was only 40 years old.
