4.5. The Pentagon The hole that was left after American Airlines Flight 77 flew into the Pentagon was much smaller than the actual commercial plane. The plane was 125 feet long, however the hole left behind was 16 feet long, which lead a lot of people to question whether it was in fact the plane that crashed into the pentagon or was it hit by a foreign object and was made to look like a plane. 4.6. United Airlines Flight 93 Despite the cockpit recordings implying that the passengers fought, overpowered the terrorist and eventually crashed the plane into the ground, people think that the plane was actually shot down.
Both airplane dropped into the canyon. There were no survivors among the 128 persons onboard the flights. The collision occurred while both of the regularly scheduled passenger service flights were flying under Visual Flight Rules (VFR) The 1956 Grand Canyon mid-air collision occurred on Saturday, June 30, 1956 at 10:30 am Pacific Average Period after a United Airlines Douglas DC-7 assaulted a Trans Globe Airlines Lockheed L-1049 Super Constellation above the Grand Canyon inside the borders of Grand Canyon Nationwide Park, resulting in the crash of both airliners. All 128 on board both flights died. It was the early business airline crash to consequence in more than 100 deaths, and led to sweeping changes in the control of flights in the United States.
the plane was 3.5 miles Southwest of the Pentagon, making a 330 degree right turn, just four miles from the Pentagon. There were two reported calls from Flight 77, one from flight attendant Renee May that was to her mother and a call from passenger Barbara Olsen to her husband, telling him how hijackers had used box cutters and knives to take over the plane. At 9:38 a.m. Flight 77 crashed into the Pentagon, killing all 64 passengers that were on the plane and taking lives of others. For the third time that day, innocent lives were taken.
The film depicts a first hand account of United flight 93 en route to Washington DC as it is presumed, however it is redirected to Pennsylvania where it ultimately crashes due to a terrorist hijacking aboard the aircraft. United Airlines Flight 93 was a domestic scheduled passenger flight that was hijacked by four Al-Qaeda terrorists on board, as part of the September 11 attacks. It crashed into a field near the Diamond T. Mine in Stonycreek Township, Somerset County, Pennsylvania. There was an attempt by some of the passengers to regain control, killing all 44 people aboard including the four hijackers. The hijackers breached the aircraft's cockpit and overpowered the flight crew approximately 46 minutes after takeoff.
As demonstrated in the case of CI611, the accident aircraft had a serious hidden structural defect. High-frequency eddy current inspection is not able to detect cracks through a doubler. The crack would still not be detected if external high-frequency eddy current had been used for structure inspection. Therefore, a more effective non-destructive structural inspection
It is 9:00 AM, American airline #11 crashed in between the 93rd-99th floor of the North Tower. 18 minutes later, the next plane, airline #175 hit the south tower. Now they are scorching into flames, and by 10:30 both towers had fallen straight down. It seems like the towers should have toppled over, but they did not, but It fell straight down. However, the planes hit so high up in the towers that the towers did not topple over, now if the planes hit lower they would have toppled over.
“The aircraft crashed after it overran the end of the runway 4R during landing (National Transportation Safety Board, 2001).” The probable cause of the accident was aircrew fatigue and situational awareness. Out of 145 people aboard the aircraft, 10 were killed in the accident including the captain. During the crash the airplane “passed through a chain link security fence and over a rock embankment to a flood plain (National Transportation Safety Board, 2001).” The aircraft was demolished due to impact as well as fire. The National Transportation Safety Board believes the probable cause of the accident was due to the crew being fatigued as well due to the inability of situational awareness while landing under unfavorable weather
American Airlines Flight 587 Title: Aircraft Accident report: In-flight separation of vertical stabilizer of American Airlines flight 587, an Airbus Industrie A300-605R aircraft on November 12, 2011. Author of this paper are Nitin Jayant (2012CE10371) & Jitesh Kumar (2012CE10355). Abstract: The aim of this paper is to explain the accident of American Airlines Flight 587, an Airbus Industrie A300-605R, registration N14053 aircraft which crashed into a residential area of Belle Harbor, New York. The aircraft’s vertical stabilizer and rudder were separated during the flight. The safety issues discussed in this paper focus on characteristics of the A300-600 rudder control system design, A300-600 rudder pedal inputs at high airspeeds, aircraft-pilot coupling, flight operations at or below an airplane’s design maneuvering speed, and upset recovery training programs.
Engineering Disasters: Concorde Air France Flight 4950 Crash (2000) Name Student ID Institution Affiliation Introduction Purpose Official reports by France’s Accident Investigation Bureau (BEA, 2001) revealed that on the Tuesday of July 25th, 2000 Concorde Air France Flight 4950 from Paris en route to New York crashed barely two minutes after takeoff from runway 26 at the Roissy Charles de Gaulle Airport. The airplane rammed into a hotel in Gonesse, France, bursting into flames and killing all the 109 passengers on board including the 9 flight crew members, and 4 other ground casualties. This catastrophic incident raised engineering concerns, which beg the following questions: What engineering design flaws led to the disaster? Whose fault was it? What future precautions and safety measures are recommended?
Just Eleven minutes into the Flight the plane exploded eight miles away from the coast of Long Island then creating from that moment on a national mystery of what had caused the plane to explode (TWA flight 800 crash - Atlantic Ocean off New York:1996 2). Soon after the aircraft was submerged in water and had been seen by many as it went down in flames, water vessels in the surrounding area were able to reach the site within minutes, but soon to be discovered all 230 people had not survived with all bodies being found and 95% of the plane being recovered (McDowell-Smith 1). With all the information before the crash being easily attained the cause for the crash was unknown which leads many to wonder what had actually caused this tragedy. The misfortunate catastrophe of the explosion of Flight 800 brought grief to many which brought people longing for an answer to bring closure
