Reentry has, of course, always been a difficult part of the space program. But this is, in fact, our first fatal accident on reentry. Apollo 13 is remembered as our most difficult ever reentry, but the ship and crew survived. The Soviets lost a crew on reentry in 1970 after an oxygen leak that caused the cosmonauts to suffocate on the way down. Reentry is a very difficult process, but the Russians mastered it in 1961 and we did the same a few years later.
More than 90% of the workers and visitors who died in the towers had been at or above the point where the plane was hit. In the North Tower 1,355 people at or above the point where the plane hit were trapped and died of smoke inhalation, fell or jumped from the tower to escape the smoke and flames, or were killed in the building's eventual collapse. The destruction of all three staircases in the tower when Flight 11 hit made it impossible for
* Frederick L. Ashworth flew with Sweeney in Bockscar and was responsible for arming the bomb. * The primary target was the city of Kokura. Nagasaki was the secondary target. * Bockscar’s reserve fuel tank was not pumping fuel correctly so the plane could not make use of the extra 600 gallons. * About 40,000 people died in this mission.
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.
The events that took place on February 1, 2003 and January 28, 1986 were without question a terrible tragedy. However, could such tragedies that took place have been avoided? The shuttle Challenger had completed 9 previous flights whereas; the shuttle Columbia had successfully completed twenty seven missions prior to the events. So what about the Challenger and Columbia’s last missions went astray and who is to blame? The Space shuttle Challenger was NASA’s second vehicle to be put into service however; on January 28, 1986 it would make its final departure from Kennedy Space Center.
As Columbia Space Shuttle launched, foam insulation came off and damage left wing’s thermal protection system. The heat of reentry destroyed the left wing and lead to the breakup of the orbiter. Challenger and Columbia Space Shuttle accidents are examples of human error and negligence. The Challenger suffered from negligence with no room to blame human imperfections. Engineers wanted to delay Challenger’s take-off; because warmer temperatures produce better launch probability.
The Fireworks up Above Tragedy strikes and every person blinks their eyes and are in denial about what just happened. Nothing in this nature has ever been seen or looked on or heard of. The US Space Challenger just exploded in a sky creating a display of fireworks. This is not a beaming, gleeful firework where there is awe of the beauty; this is a firework that shows nothing but disaster and tragedy for this firework carried people. The US Space Challenger was an event that woke up America and made NASA stop and think about the reality just faced: “The Challenger disaster was a severe blow to the American space program” (On this Day n.p.).
The fourth plane crashed into a field near Shanksville in rural Somerset County, Pennsylvania, after some of its passengers and flight crew were said to attempt to retake control of the plane. 2,999 people were estimated as dead, and a massive 6, 291+ were considered injured. On this date, 9/11, I was 11 years old in the 5th grade of grammar school. At that time I never went to New York before, but it to me is a massive city with a lot of pride and tradition. The though of the actions that were taking on this day by terrorists shocked me as a kid and
The second plane hit the South tower of the World Trade Center around 9:02 A.M. (911 timeline). Both of these towers are monumental buildings that couldn’t withstand the impact of the crashes. Within two hours the buildings had collapsed to the ground. The third plane was flown into the Pentagon building in Washington, D.C. at around 9:37 A.M. (911 timeline). Finally, the fourth plane crashed into a field in the rural area of Pennsylvania around 10:03 A.M. (911 timeline).
On April 11th, NASA launched their third manned mission to the moon, Apollo 13. Two days later, April 13th, at exactly 13:13 Central Standard Time, one of the oxygen tanks exploded, resulting in a power shortage and failure of the two remaining oxygen tanks. The space shuttle never made it to the moon and the mission was deemed a failure. Many people believed that this was a result of the mission being numbered 13. A number considered by many to be unlucky.
