Case study chapter 12 the challenger and columbia shuttle disasters

EST, February 1, The Flight Control Team had not been working on any issues or problems related to the planned de-orbit and re-entry of Columbia. In particular, the team had indicated no concerns about the debris that hit the left wing during ascent, and treated the re-entry like any other.

The team worked through the de-orbit preparation checklist and re-entry checklist procedures. Weather forecasters, with the help of pilots in the Shuttle Training Aircraftevaluated landing-site weather conditions at the Kennedy Space Center.

All weather observations and forecasts were within guidelines set by the flight rules, and all systems were normal. A 2-minute, second de-orbit burn during the th orbit slowed the Orbiter to begin its re-entry into the atmosphere. The burn proceeded normally, putting the crew under about one-tenth gravity.

Husband then turned Columbia right side up, facing forward with the nose pitched up. Columbia at about 8: Debris is visible coming from the left wing bottom. A sensor on the left wing leading edge spar showed strains higher than those seen on previous Columbia re-entries. This was recorded only on the Modular Auxiliary Data System, which is similar in concept to a flight data recorderand was not sent to ground controllers or shown to the crew.

Columbia executed a planned roll to the right. Columbia began a banking turn to manage lift and therefore limit the Orbiter's rate of descent and heating.

Columbia entered a minute period of peak heating, during which the thermal stresses were at their maximum. Columbia crossed the California coast west of Sacramento. Various people on the ground saw signs of debris being shed. The superheated air surrounding the Orbiter suddenly brightened, causing a streak in the Orbiter's luminescent trail that was quite noticeable in the pre-dawn skies over the West Coast.

Dialogue on some of the amateur footage indicates the observers were aware of the abnormality of what they were filming. In Mission Control, re-entry had been proceeding normally up to this point. Columbia crossed from California into Nevada airspace. Witnesses observed a bright flash at this point and 18 similar events in the next four minutes.

Columbia crossed from Nevada into Utah. Columbia crossed from Utah into Arizona. Columbia began a roll reversal, turning from right to left over Arizona. Columbia crossed from Arizona to New Mexico. Columbia passed just north of Albuquerque.

Columbia crossed from New Mexico into Texas. At about this time, the Orbiter shed a Thermal Protection System tile, the most westerly piece of debris that has been recovered.

Searchers found the tile in a field in Littlefield, Texasjust northwest of Lubbock. A broken response from the mission commander was recorded: Hydraulic pressure, which is required to move the flight control surfaces, was lost at about 8: At that time, the Master Alarm would have sounded for the loss of hydraulics, and the shuttle would have begun to lose control, starting to roll and yaw uncontrollably, and the crew would have become aware of the serious problem.

Videos and eyewitness reports by observers on the ground in and near Dallas indicated that the Orbiter had disintegrated overhead, continued to break up into smaller pieces, and left multiple ion trails, as it continued eastward. In Mission Control, while the loss of signal was a cause for concern, there was no sign of any serious problem.The Hollywood Reporter is your source for breaking news about Hollywood and entertainment, including movies, TV, reviews and industry blogs.

Watching the Housing Detectives. It’s been an exciting 10 days, to say the least so bear with me while I spin my yarn.

The potential of the research method advocated above is illustrated by two studies of organisational cultures that I have carried out (Hopkins, , p. 23–).The first of these was a study of the culture of the rail organisations in the Australian state of New South Wales.

It started with a trip to the epic Appraiserfest in San Antonio, Texas, hence my “placeholder” Housing Notes last week. The event was a rousing success for the underrepresented residential appraisers across the U.S and was the talk of D.C. regulators (in a good way.

NASA Shuttle Case Study Introduction For this assignment we will discuss some theories on organizational change learned during this class and how they relate to the case study of NASA (The Challenger and Columbia Shuttle Disaster).
