    CAIB also discussed the organizational causes of the accident in space shuttle program history and culture that included original concessions that were needed to obtain support for the shuttle’s subsequent years of resource constraints, fluctuating priorities, schedule pressures, mischaracterization of the shuttle as operational rather than developmental, and lack of an agreed national vision for human space flight (CAIB, 2003, p.9).
    The culture at NASA was highly criticized. The NASA organizational culture had as much to do with this accident as the foam. Organizational culture refers to the basic values, norms, beliefs, and practices that characterize the functioning of an institution. At the most basic level, organizational culture defines the assumptions that employees make as they carry out their work. It is a powerful force that can persist through reorganizations and the change of key personnel. It can be a positive or a negative force (CAIB, 2003, p.97).

    Due to the loss of Space Shuttle Columbia, the Shuttle fleet was grounded in an effort to provide an internal and external independent investigation into the loss of the Space Shuttle Columbia as it re-entered the earth's atmosphere (Aerospaceguide, 2009).
    The Investigation

    The Board’s statement of introduction said that the “aim [of the investigation] has been improve shuttle safety by multiple means, not just by correcting the specific faults that cost the nation this orbiter and this crew. With that intent, the Board conducted not only an investigation of what happened to Columbia, but also to determine the conditions that allowed the accident to occur a safety evaluation of the entire space shuttle program” (CAIB, 2003, p.6).
    The report confirmed that the physical cause of the loss of Columbia and its crew was a breach in the Thermal protection system on the leading edge of the left wing, caused by a piece of insulating foam which separated from the left bipod ramp section of the external tank at 81.7 seconds after launch, and struck the wing in the vicinity of the lower half of Reinforced Carbon-Carbon panel number 8. During re-entry this breach in the thermal protection system allowed superheated air to penetrate through the leading edge insulation and progressively melt the aluminum structure of the left wing, resulting in a weakening of the structure until increasing aerodynamic forces caused loss of control, failure of the wing, and breakup of the Orbiter. This breakup occurred in a flight regime in which, given the current design of the Orbiter, there was no possibility for the crew to survive (CAIB, 2003, p.9).

    Space shuttle Columbia (OV-102) was the oldest of NASA's fleet of space planes. Construction started in 1975. In April 1981, Columbia became the first shuttle to fly in space following the successful atmospheric test flights of its sister ship Enterprise. The maiden flight - piloted by veteran astronauts John Young and Robert Crippen heralded a new era in space exploration. The shuttle was the world's first reusable space vehicle. Before the shuttle, manned spaceflight had been limited to vast, expensive rockets which could only be used once. On the second mission, in November 1981, astronauts aboard Columbia carried out the first scientific experiments of the shuttle program. They also tested the shuttle's trademark robot arm. Joined by its sister ships Challenger, Discovery, Atlantis and later Endeavour, Columbia went on to carry out a further 27 successful missions. In 1996 astronauts aboard Columbia notched up the record for the longest shuttle flight, spending 35 days orbiting the Earth. Despite being the oldest in the fleet, Columbia had been extensively refurbished several times.
    The Space Shuttle Columbia was launched on January 16th, 2003 at 9.39am CST. Columbia was on a 16-day science research mission in Earth orbit which carried out experiments in space. Columbia was NASA’s oldest space shuttle in the fleet of four. It was the first space shuttle to be launched in Earth orbit in 1981.
