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.
History of South Carolina
Similar views were developed in scholarly monographs by academic historians of the Dunning School based at Columbia University in the early 20th century; they served as historians at major colleges in the South, influencing interpretation of Reconstruction into the 1960s. They argued that corrupt Yankee carpetbaggers controlled for financial profit the mass of ignorant black voters and nearly plunged South Carolina into economic ruin and social chaos. The heroes in this version were the Red Shirts: white paramilitary insurgents who, beginning in 1874, rescued the state from misrule and preserved democracy, expelled blacks from the public square by intimidation during elections, restored law and order, and created a long era of comity between the races.
