As Columbia Space Shuttle launched, foam insulation came off and damage left wing’s thermal protection system. The heat of reentry destroyed the left wing and lead to the breakup of the orbiter. Challenger and Columbia Space Shuttle accidents are examples of human error and negligence. The Challenger suffered from negligence with no room to blame human imperfections. Engineers wanted to delay Challenger’s take-off; because warmer temperatures produce better launch probability.
Visual meteorological conditions prevailed for the flight, which operated on an instrument flight rules flight plan (National Transportation Safety Board, 1996a). The National Transportation Safety Board determines that the probable cause of the TWA flight 800 accident was an explosion of the center wing fuel tank (CWT), resulting from ignition of the flammable fuel/air mixture in the tank. The source of ignition energy for the explosion could not be determined with certainty, but, of the sources evaluated by the investigation, the most likely was a short circuit outside of the CWT that allowed excessive voltage to enter it through electrical wiring associated with the fuel quantity indication system (National Transportation Safety Board, 1996a). Structural and Mechanical Factors (Two to four paragraphs identifying the structural and mechanical factors involved in this accident.) Contributing Factors Contributing factors to the accident were the design and certification concept that fuel tank explosions could be prevented solely by precluding all ignition sources and the design and
This plane had four hijackers on board the flight. On this flight, the passengers revolted against the hijackers and crashed the plane on the ground in Shanksville, Pennsylvania at 10:03 a.m. Experts believe that Flight 93 was headed to either the Capitol building or the White House (September 11, 2001, Terrorist Attacks). Out of the four hijackings, two of the planes
William McAuley Composition Mrs Barnes 13 March 2013 A total of almost 3 thousand civilian lives were lost on September 11, 2001. Sixteen hijackers used 4 planes to attack the USA . One plane the Pentagon, one plane hit each twin towers and one was taken over by passengers and crashed in Pennsylvania. September 11, 2001 two thousand was the day America realized that its national security had been compromised by another country. There were 4 hijackers that flew 2 planes into the twin towers and a total of 16 hijackers four in four planes.
The third was crashed into the Pentagon and the fourth in a field during a struggle between passengers and hijackers to control the airplane. An investigation conducted after the attacks concluded that members of al-Qaeda planned and orchestrated the attacks.
* Frederick L. Ashworth flew with Sweeney in Bockscar and was responsible for arming the bomb. * The primary target was the city of Kokura. Nagasaki was the secondary target. * Bockscar’s reserve fuel tank was not pumping fuel correctly so the plane could not make use of the extra 600 gallons. * About 40,000 people died in this mission.
This was indeed one of the biggest problems during the campaign. Supplies were dropped along the Kokoda track by aircraft known as the ‘Biscuit Bombers’ (Australian Government Department of veteran affairs (2014) About the Kokoda track: 1939 to 1942). Many of these supply drops missed their target area. As they were dropped from a high altitude, many of the supplies smashed when they hit the ground. (Australian Government Department of veteran affairs (2014) About the Kokoda track: 1939 to 1942).
Martin Guardado Dr. Long English 350 03/02/15 The Demolition in 9/11 On 9/11 two passenger planes struck The Twin Towers of The World Trade Center, and moments later the two buildings collapsed. It appears that the reason behind the collapse was because of the impact of the plane and the fire that followed. To others, such as some survivors, non-governmental researchers, engineers, and scientists that have studied or witnessed the collapse, it appears as a demolition. Despite the reasons for the collapse of the twin towers and building 7 on the official report of 9/11 by the government and the authority figures associated with it, other non-government figures such as researchers, engineers, scientist and surviving witnesses provide a clearer explanation on what caused the buildings to collapse. On the official report of 9/11 it says that the collapse happened because of the fire in the buildings, but regardless other evidence contradicts this theory.
The autopilot wasn’t working that day so the pilot pulled up with the intention of circling around and trying the landing again. On the way back to the runway the engines died and the plane crashed, killing 158 people. It had run out of gas. How the plane was able to crash because of low fuel, despite the fact that both the pilot and first officer could see the fuel gauge becomes clear upon investigation of the black box. The transcript of their conversation during the initial landing, into heavy fog, is as follows: Caviedes: The runway, where is it?
