The Challenger was a space shuttle of great experience. Before its last journey it had witnessed the first steps of man and the first woman on the moon. It was named after the British Naval research vessel that sailed the Atlantic and Pacific Ocean during the 1870’s. The Challenger certainly made its scientific contribution to the sense of exploration because the Apollo 17 also carried the name Challenger (Space Shuttle Overview: Challenger n.p.). The next and last journey of the space shuttle was on January 28, 1986 when the US Space Challenger broke apart seventy-three seconds after lift off.
The Challenger and Columbia Space Shuttle accidents During the Challenger and Columbia Space Shuttle accidents, there were key factors that contributed to each incident. In the midst of take-off, the Challenger began to leak hot combustible gases, which cause the destruction of the space shuttle. The leak happened between the O-ring and SRB segments and the explosion was inevitable. The Columbia tragedy had begun at launch and reentry. As Columbia Space Shuttle launched, foam insulation came off and damage left wing’s thermal protection system.
Michael Squillacote 9/28/11 Professor Blum Business paper Challenger Shuttle The Challenger space shuttle was set off to launch on January 28th 1987. This turned into a tragic day for NASA and the United States. At 11:38 am Challenger took of from the launch pad. Everything was going smoothly until 73 seconds into the flight the shuttle disintegrated over the Atlantic Ocean killing seven astronauts. There are a few different theories on what went wrong to the shuttle.
This time, 40,000 were killed instantly, and another 40,000 due to injuries and radiation. Common descriptions of the bombing include a "mushroom cloud", an extremely bright flash of light that caused blindness, severe burns (skin hanging from people, eyes burnt, people turned into ash etc. ), and the entire area being literally flattened. It was said that the heat produced was equivalent to the sun, and that the force of one atomic bomb was equivalent to 67 million sticks of dynamite! After the war, atomic bombs have never been used again.
Flight 11 crashed into the North Tower at 8:46 a.m. Eastern Time, and 17 minutes later, Flight 175 crashed into the South Tower. Most people called 911 screaming "Help," but they did not know where they was inside the building. Both towers collapsed creating a massive cloud of smoke that ran through New York. The South Tower collapsed
A meteor struck the moon and moved it closer into orbit changing centrifugal forces and causing worldwide tidal waves, earthquakes, volcanic eruptions, and that’s just the start. Without a care in the world is how Miranda’s life was at the beginning. A normal lifestyle is what she lived. She lost her best friend when Becky passed away. That was the cause of Miranda, Sammi, and Megan to grow apart, and their strong friendship would never be the same.
The buildings went up in flames as people attempted to flee from the ash, steel, glass, and bodies falling from above. Both buildings, which took a total of eight years to construct, collapsed in less than 90 minutes. That same morning, at 9:37, a third plane crashed into the Pentagon, just outside of Washington. Then, at 10:03, the fourth and final plane crashed into a field in southern Pennsylvania. (National Commission on Terrorist Attacks upon the United States) The hijackers on this plane intended to slam into The White House, but heroic passengers managed
The incident occurred at an altitude of some 200,000 feet, shortly after reentry and 15 minutes before Columbia had been scheduled to land at Cape Canaveral. TIME science correspondent Jeffrey Kluger explains some of the possible causes and consequences of the accident: TIME.com: What are the possible scenarios that could have caused this disastrous accident on the shuttle's reentry into the Earth's atmosphere? Jeffrey Kluger: There are three possible scenarios that explain this event. The first, which I believe is the likeliest explanation, would be an aerodynamic structural breakup of the shuttle caused by it rolling at the wrong angle. Remember, after reentry, the shuttle is descending without power, which means astronauts at the controls can't compensate for a loss of attitude by using the engines, they can only do so using the flaps.
The first crash happened a couple of minutes before 9.00am and the second plane 18 minutes later. By 10.30 the structures of both trade centres had collapsed. At about the same time two other planes were hijacked one was crashed into the pentagon in Washington D.C. The pentagon is the headquarters of the U.S defence department; witch is the agency of the government that controls the military. The fourth plane crashed into an open field in western Pennsylvania.
The FBI found no traces of explosives at the crash sites, and the 9/11 Commission concluded the bombs were probably fake. Three buildings in the World Trade Center Complex collapsed due to structural failure. The South Tower collapsed at 9:59 a.m. after burning for 56 minutes in a fire caused by the impact of United Airlines Flight 175. The North Tower collapsed at 10:28 a.m. after burning for 102 minutes. When the North Tower collapsed, debris fell on the
