On January 28, 1986, on the twenty-fifth mission of the shuttle program, the shuttle Challenger exploded into flames shortly after lift-off. A presidential commission eventually identified the cause of the explosion as a failure of the joints on a booster rocket to seal. “The 'culprits' were the synthetic rubber O-rings that were designed to keep the rockets' super hot gases from escaping from the joints between the booster's four main segments. Resulting flames then burned through the shuttle's external fuel tank. Liquid hydrogen and liquid oxygen then mixed and ignited, causing the explosion that destroyed the Challenger" (Palmer, Dunford, & Akin, 2009, p. 375).
On a Tuesday morning Spetember 11, 2001, a tragedy struck the United States and it changed the course of history. World Trade Center Twin Towers and the Pentagon were targeted by hijacked aircraft, killing thousands, and initiating the death of almost a million in the name of the victims of 9/11. An act of terror was committed, regardless of whom the committer was. Such a horrendous act deserves a genuine unbiased investigation, which the United States government failed to provide. The 9 11 Commission report, set out to “prepare a full and complete account of the circumstances surrounding the September 11, 2001 terrorist attacks”, found out that 19 arab hijackers led by Osama Bin Laden breached the Unites States’ defense system, crashed into the twin towers and pentagon, and eventually resulted in structural failure of the Twin Towers leading to the collapse.
The impact of this disaster will be analyzed. Not only the impact that was made on the families of the victims lost, but also the impact of the disaster that was made on the airline industry. In conclusion, a discussion about improvements was included to be better organized in the event a similar disaster was to take place. THE CRASH OF VALUJET FLIGHT 592 On May 11, 1996 a Douglas DC-9 crashed into the Everglades about 20 minutes after takeoff from Miami International Airport (MIA), Miami, Florida. It was determined that this DC-9 was a plane operated by ValuJet Airlines as flight 592.
JetBlue – Valentine’s Day Massacre - Case Study MBA525 27 May 2014 JetBlue – Valentine’s Day Massacre - Case Study From being called the “Valentine’s Day from hell” to the “Valentine’s Day Massacre”, February 14, 2007 will likely go down as the worst day in JetBlue's history. The winter storm that blasted the Midwest and Northeast wreaked havoc with travelers and airlines alike. It started as a winter ice storm forecasted to change to rain. JetBlue officials at New York’s John F. Kennedy Airport gambled that temperatures would warm up enough to change the snowfall and icy slush into rain. (Argenti, 2013 p. 104).
The ESCO Corporation developed the Engineered Arresting Systems (EMAS) to provide airports with an answer to the runway overrun problem. The EMAS system proved to be so successful that the FAA approved to pay for the systems to be installed in airports. What is the runway overrun issue? Basically a runway overrun is when an airplane goes off the end of the runway; either on takeoff or landing. The Federal Aviation Administration (FAA) and National Transportation Safety Board (NTSB) information, have reported that runway overruns during landing.
Case Study Analysis Activity Title: American 191 Name: Date: 20 Apr 2012 Cause(s) of Accident (Two to four paragraphs identifying the probable causes of the accident.) The causes for this aircraft accident, identified in the National Transportation Safety Board(NTSB) Aircraft Accident Report(AAR) 79-17, shows that just after the aircraft reached takeoff speed the number one engine and pylon assembly separated from the wing. When this pylon separated it also pulled a three foot section from the leading edge of the left wing. As previously mentioned the aircraft had already obtained take off speed and continued to takeoff. The aircrew was under the impression at the time that the engine had only failed.
A Court of Inquiry was held and the accident investigation was given to the Royal Aircraft Establishment at Farnborough. By using debris recovered from the Elba crash and using a known good airframe to do pressurized hull testing in a water tank, the causes of these accidents were traced to structural failure around the square windows and ADF antenna mounts due to metal fatigue. The Comet fleet was grounded while the lessons learned from these crashes were implemented into the next generation of Comets. Unfortunately for de Havilland, Boeing had taken the findings from the investigation and applied them to jet aircraft still on the drawing board. These improvements in metallurgy and design aided Boeing in dominating the world market in producing commercial jet aircraft that were larger and had longer ranges than the Comet.
CIS518 Assignment 1 Submitted by: Mohammad Shahriar Professor: Dr. Edwin Otto Strayer University EXERCISES - 1 PILOT’S COMPUTER ERROR CITED IN PLANE CRASH. AMERICAN AIRLINES SAYS ONE-LETTER CODE WAS REASON JET HIT MOUNTAIN IN COLOMBIA. Dallas, Aug. 23—The captain of an American Airlines jet that crashed in Colombia last December entered an incorrect one-letter computer command that sent the plane into a mountain, the airline said today. The crash killed all but four of the 163 people aboard. American’s investigators concluded that the captain of the Boeing 757 apparently thought he had entered the coordinates for the intended destination, Cali.
2) INTRODUCTION A bombardier DHC8-402 Q400 operating as Continental Connection Flight 3407 departed late from Newark on 12th February, 2009 at 2120 EST. The Flight was on an instrument approach to Buffalo- Niagara International Airport, but suddenly at 2217 EST it lost the radar connection and led to the mishap of Colgan Flight 3407 killing 2 pilots, 2 flight attendants, 45 passengers and 1 resident. The NTSB investigated the crash within a year of the accident. The NTSB found out that
6) Flight Leader Lt. Taylor requested the flight to be grounded — he was ordered to fly. 7) The first leg of the Navigation Problem didn’t find their target (see #1) 8) Up to 60 knot northerly winds came up in a storm and blew them into the northern Bahamas. The irony of Flight 19 is that none of the men died within the infamous Bermuda triangle. Three crash sites have been located and one aircraft has been raised from the sea. Flight 19 was discovered in 1991 in August of that year.
