SIGMET stands for Significant Meteorological Hazards. A SIGMET can be issued for one of four reasons. First, severe icing not associated with thunderstorm activity. Second, severe turbulence not associated with thunderstorm activity. Third, dust storms and sandstorms. Fourth would be volcanic Ash. There is also Convective SIGMETs. Convective SIGMETs include embedded thunderstorms, a line of thunderstorms, surface winds greater then 50 knots, hail with a diameter greater then ¾ inch, and tornadoes (SIGMETs, n.d.). In the case of Air Florida Flight 90 there was only a SIGMET issued. The SIGMET was issued at 1340 and was valid until 1740. The SIGMET
On the morning of the 25th of September an employee with Big Island Air who said they had seen the pilot that morning when he arrived at the airport, mentioned that he appeared to look rested and very alert.

At 9:03 United Airlines Flight 175 crashes in the South Tower of the World Trade Center. American Airlines Flight 77 crashes into the western façade of the Pentagon. While United Airlines Flight 93’ some believed it was destined for the White House, U.S. Capitol building, or other landmarks, crashes into a field in Somerset County, Pennsylvania.

On September 11th, 2001 at the World Trade Center 2,749 people were killed when hijacked American Airlines Flight 11 and United Airlines Flight 175 were crashed into the north and south towers. 412 of them were rescue workers who came to help. 147of them were passengers or crew members on the two flights. 102 Minutes by Jim Dwyer and Kevin Flynn, the title referring to the time between when the first airplane hit the north tower and the south tower collapsed, tells the stories of what is happening inside the Twin Towers on September 11th and the fight for survival under unimaginable conditions.
An Eastern Air Lines Lockheed L-1011 crashed at 2342 eastern standard time, December 29, 1972, 18.7 miles west-northwest of Miami International Airport, Miami, Florida. The aircraft was destroyed.

On the morning of September 11/2001, 19 terrorist working for the Al Qaeda terrorist organization hijacked four commercial planes. They attempted to fly them into multiple U.S targets. One of the planes, American Airlines, flight 11, crashed into the north tower of the World Trade Center at 8:50 a.m. Another plane, United Airlines, flight 175, crashed into the south tower at 9:04 a.m. These tragedies took the lives of nearly 3000 people and affected the lives of millions.
Flight 93, the flight that crashed near some fields in the outskirts of Pennsylvania. But what was it doing there? What caused the plane to miss its target and crash? These answers may soon be revealed when detectives can finally examine the planes black box, found just recently. Many answers however can be found through other pieces of info that have come up along the way during the investigations.
The Colgan Air Flight 3407 was a very interesting case to look at. On February 12, 2009, at 10:17 pm, flight 3407 crashed at a house in New York after the pilots experience a stall. Flight 3407 was scheduled to fly from Newark, New Jersey to Buffalo, New York. The NTSB reported the cockpit voice recorder (CVR) revealed some discrepancies both pilots were experience. The first officer did not have any experience with icing condition but icing was one of the reasons the plane went into a stall. On the other hand, the captain had some experience flying in icing condition. The captain was experiencing fatigue, which indeed, made him unfit to recover from a stall. With that in mind, the Human Factor Analysis Classification System (HFACS) will give insight of some errors both pilots made.

It was the afternoon of July 25, 2000. One hundred passengers, most of them German, boarded the Concorde Air France Flight 4590. This was a trip of a lifetime for many people, as Concorde was restricted to the wealthy class of people.
