Nearly 3, died during the attacks, and many more suffer ongoing conditions from injuries and smoke inhalation. For millions, September 11, , is a day that will never be forgotten. Have you read? An entire generation of Americans has no idea how easy air travel used to be. There were four planes involved in the crash.
Life in America was set on a new trajectory. It took media sites minutes to start coverage of the crash. I figured it would be on the evening news and continued to get ready for work and take the dog out.
Well, it didn't end as a work day. I thought it odd that a plane would be so low and making such an odd noise on a clear day. Usually, the only days when planes were low over lower Manhattan were in bad weather for whatever reason. I would guess no faster than this. The Vmo max operating speeds on transport category aircraft down low is usually in the knot range. Now that is a design limit speed to prevent structural damage. The plane can physically go faster.
Above that the airplanes warning systems get quite annoying. It is not likely but you do risk structural failure. Those guys would have known enough to know that wanted to hit their target intact without ripping the wings off short of the target and any additional speed over that would have made it increasing harder to accurately maneuver into the building. Also the warning systems going bananas for an overspeed really distract you and they probably wanted to focus on the task at hand.
The comment about the airplane being on a glide with no power is not accurate. If the engines were at idle you would not be able to hear that sound over the running motor. You can hear that sound on the ramp when it is quiet, the engines are off and the wind is rotating the fan blade. You would never hear that from a running engine. Even at idle it is spinning very fast. There is no way the engines were completely shut off when they impacted the building.
The rattling sound was more likely a speed induced airframe buffet due to the high speed. Second, maybe the first plane, but you can see on the video that the second plane was gettin it. Ill take the expert answer over what someone heard inside a building who asked someone else who isnt an expert their opinion based on description of a sound second hand. Im not sure how it really matters though. The 19 terrorists easily smuggled box-cutters and knives through security at three East Coast airports and boarded four early-morning flights bound for California , chosen because the planes were loaded with fuel for the long transcontinental journey.
Soon after takeoff, the terrorists commandeered the four planes and took the controls, transforming ordinary passenger jets into guided missiles. Jet fuel from the Boeing caused a devastating inferno that led to the structural collapse of a portion of the giant concrete building, which is the headquarters of the U. Department of Defense. All told, military personnel and civilians were killed in the Pentagon, along with all 64 people aboard the airliner. Less than 15 minutes after the terrorists struck the nerve center of the U.
The structural steel of the skyscraper, built to withstand winds in excess of miles per hour and a large conventional fire, could not withstand the tremendous heat generated by the burning jet fuel. At a. Only six people in the World Trade Center towers at the time of their collapse survived.
Almost 10, others were treated for injuries, many severe. Because the plane had been delayed in taking off, passengers on board learned of events in New York and Washington via cell phone and Airfone calls to the ground. Knowing that the aircraft was not returning to an airport as the hijackers claimed, a group of passengers and flight attendants planned an insurrection. One of the passengers, Thomas Burnett, Jr.
I love you, honey. Sandy Bradshaw, a flight attendant, called her husband and explained that she had slipped into a galley and was filling pitchers with boiling water. The passengers fought the four hijackers and are suspected to have attacked the cockpit with a fire extinguisher.
The plane then flipped over and sped toward the ground at upwards of miles per hour, crashing in a rural field near Shanksville in western Pennsylvania at a. All 44 people aboard were killed. Its intended target is not known, but theories include the White House , the U. Capitol, the Camp David presidential retreat in Maryland or one of several nuclear power plants along the eastern seaboard.
