Painstaking work by the Columbia Accident Investigation Board (CAIB) later identified the physical cause of the disaster as damage to Columbia's left wing that occurred just 81.9 seconds after launch.
A piece of insulating foam separated from the left "bipod ramp" that connected the shuttle's fuel tank to the orbiter, gouging a hole in a reinforced carbon-carbon (RCC) panel on the leading edge of Columbia's left wing.
Now, 10 years later, new information is coming to light on an event early in Columbia's mission, often termed the "Flight Day 2 Object."
When added to the wealth of information already known about how the Columbia accident occurred, this story reinforces a picture of technical slip-ups, a lack of effective communications and a failure of early detection and reaction to anomalies, all of which contributed to the disaster.
