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 University
In 1763, Dr. Johnson was succeeded in the presidency by Myles Cooper, a graduate of The Queen's College, Oxford, and an ardent Tory. In the charged political climate of the American Revolution, his chief opponent in discussions at the college was an undergraduate of the class of 1777, Alexander Hamilton. The American Revolutionary War broke out in 1776, and was catastrophic for the operation of King's College, which suspended instruction for eight years beginning in 1776 with the arrival of the Continental Army. The suspension continued through the military occupation of New York City by British troops until their departure in 1783. The college's library was looted and its sole building requisitioned for use as a military hospital first by American and then British forces. Loyalists were forced to abandon their King's College in New York, which was seized by the rebels and renamed Columbia College. The Loyalists, led by Bishop Charles Inglis fled to Windsor, Nova Scotia, where they founded King's Collegiate School.
