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 (electoral district)
Columbia was a provincial electoral district in the Canadian province of British Columbia. It made its first appearance on the hustings in the election of 1903. It lasted until the 1928 election, after which the revised riding was renamed Columbia River. This riding was later merged with the Revelstoke riding to become Columbia River-Revelstoke, the current riding for the western part of the area. The eastern part of the riding is now part of East Kootenay.
