Space Shuttle thermal protection system
On February 1, 2003, the Space Shuttle "Columbia" was destroyed on reentry due to a failure of the TPS. The investigation team found and reported that the probable cause of the accident was that during launch, a piece of foam debris punctured an RCC panel on the left wing's leading edge and allowed hot gases from the reentry to enter the wing and disintegrate the wing from within, leading to eventual loss of control and breakup of the shuttle.
Columbia, South Carolina
Reactivated Camp Jackson became Fort Jackson in 1940, giving the military installation the permanence desired by city leaders at the time. The fort was annexed into the city in the fall of 1968, with approval from the Pentagon. In the early 1940s, shortly after the attacks on Pearl Harbor which began America's involvement in World War II, Lt. Colonel Jimmy Doolittle and his group of now-famous pilots began training for the Doolittle Raid over Tokyo at what is now Columbia Metropolitan Airport. They trained in B-25 Mitchell bombers, the same model as the plane that now rests at Columbia's Owens Field in the Curtiss-Wright hangar.
