Footage of the debris strike at T+81.9 seconds Columbia launched from the Kennedy Space Center Launch Complex 39A (LC-39A) at 10:39:00 am. At T+81.7 seconds a piece of foam approximately 21 to 27 inches (53 to 69 cm) long and 12 to 18 inches (30 to 46 cm) wide broke off from the left bipod on the ET. At T+81.9 seconds the foam struck the reinforced carbon-carbon (RCC) panels on Columbia's left wing at relative velocity of 625 to 840 feet per second (426 to 573 mph; 686 to 922 km/h).[5]: 34  The foam's low ballistic coe
