The terrorist attacks on 9/11 have caused many debates over the years since they occurred back in 2001. Two American planes were hijacked and ran into the twin tower buildings, another was hijacked and headed for the pentagon, but thankfully never made it. Thousands of Americans lost their lives on the days of the attacks and to this day the sorrow hangs with us. Security was a huge debate of the time because America is supposed to be the safest nation there is, so how did this happen? America had lots of changes to make the attacks on September 11, 2001.
Initally, al-Qaeda considered targeting nuclear power plants on 9/11, but decided to go against it because they feared it would get too out of control. Four passenger airlines, all of which departed from airports in the northeastern United States bound for California, were hijacked by 19 al-Qaeda members. One plane hit the Pentagon just outside of Washington D.C., the second plane crashed in a field in Pennslyvania, and the last two planes crashed into the Twin Towers. Within one hour and 42 minutes both 110 story towers were completely on the ground, with debris filling the air and fires starting to spread. Numerous other buildings at the World Trade Center site in lower Manhattan were destroyed or badly damaged.
On January 28th 1986 the space shuttle Challenger launched and exploded only 73 seconds into flight shocking the world and killing the crew of seven. This disaster left the NASA community and its various engineering teams baffled to explain the disaster and some not surprised; while all wanted answers to questions as to why and how this disaster could have occurred, while some already held the data on what could have been the factors for disaster. 2 Research performed indicates there were a number of communication problems both internally with NASA and their Engineering team at Morton –Thiokol Engineering that lead to the disaster in question, specifically poor communication between NASA and the Engineering firm Morton –Thiokol Engineering, the designer of the Solid Rocket Booster (SRB), that was discovered after the accident through analysis of existing and post launch data. More specifically this paper will discuss engineering concerns about O-ring design of the (SRB) brought to the attention of NASA
Events such as the moon landing and the first airplane at Kitty Hawk show the sheer mettle of humans. One event that especially shows these characteristics is the Challenger crash in 1986. Challenger crashed after the rocket booster failed and 7 people died. This event was similar to Roanoke, and humans could have ditched
Seventy-three seconds after liftoff, “… the shuttle exploded in a forking plume of smoke and fire”(CT), as the people below watched their loved ones in their final moments. The astronauts that boarded the space shuttle Challenger on that cold morning took a huge risk by proceeding with the launch, despite the unfavorable weather conditions. Almost 30 years later, the Challenger tragedy is still a memorable event to this day. Everyone should take risks because they would never know the rewards or consequences, unless they try. Feeling a sense of pride after taking a big risk is a reward in itself.
2 seconds later, Flasher then comes and goes to the crash. When he got to the crash, he then sees that there was a bomb inside the spaceship. The bomb had a timer until it exploded. Flasher told everyone to evacuate immediately. So every started running away towards the exit except for the people who couldn’t get out of the roller coaster.
On February 1, 2003, the Space Shuttle Columbia came crashing down from space, killing all seven crew members that were present in the shuttle. The crew was an ethnically diverse group of seven, consisting of, Rick Husband, commander; Michael Anderson, payload commander; David Brown, mission specialist; Kalpana Chawla, mission specialist; Laurel Clark, mission specialist; William McCool, pilot; and Ilan Ramon, payload specialist from the Israeli Space Agency. During the 16 days in space NASA investigated a piece of foam that fell from the shuttle at its initial takeoff, it attached the external tank to the shuttle the foam fell off and struck the left wing of the shuttle. On February 1, 2003, the shuttle made its landing approach to Houston,
Marshall University Tragedy A film that was based on a true, heartbreaking event in history was We Are Marshall. The movie was based on the tragedy of Marshall University’s 1970 football season. The football team, the coaching staff, boosters, and fans were on the famed flight. Seventy-five passengers were on-board the plane, to take off in North Carolina, only for none to survive their fate of the plane crash. The movie We Are Marshall genuinely portrayed by all of the writers and actors and actresses.
Speeches for the Fallen: Pericles vs. Reagan Countless events throughout history have led to the much appreciated sacrifices of fellow humans, and one way for the community to honor this is to speak about it. Speeches such as Pericles’ Funeral Oration and Ronald Reagan’s Address to the Nation on the Explosion of the Space Shuttle Challenger have been influenced by the same ideas and structures that created a lasting effect on their audiences. Both men talk about very grave subjects: honoring men and women lost performing their duties. Pericles addressed the loss of Athenian soldiers to battles against Sparta in ancient Greek times, while Ronald Reagan gave an on-the-spot speech over the relatively recent loss of astronauts during NASA’s Challenger mission. The speeches should have made a serious and
The mission ended due to an unfortunate cabin fire during the launch test on January 27th. The Apollo 7 mission was to last 10 days and 20 hours. The three crewman were, the Commander Walter M. Schirra, the Command Module Pilot, Donn F. Eisele, and the Lunar Module Pilot, R. Walter CunningHam. The launch date was October 11, 1968. There were two goals set for this Apollo mission.
