Airline Safety essays

Airline Safety essays If you only had to pay for one fourth of your harmful actions or serve one fourth of your jail term, would you be happy? On average major airlines only have to pay a quarter for every dollar of fines that they are issued by the FAA, the Federal Aviation Administration (Staller, Most Fines Get Watered Down, usatoday.com). This can be true in cases that involve forgetting to complete paperwork to not screening luggage for explosives. Some people believe that air travel is one of the safest forms of transportation, while others question its safety. This report will examine the factors, points of views, and statistics of airline incidents that involve safety. When flying, the passengers of a commercial airline have many more things to worry about then getting to their destination on time. They have to be concerned about their personal safety. Many politicians and airplane passengers should and are worried about airline safety. Some of these worries include what condition the plane is in, who is flying the plane, and the new threat of what some experts call, falling baggage. Most federal regulators give airlines flexibility, but a typical maintenance schedule is usually followed by all of the airlines according to Boeing Corporation, a manufacturer of commercial planes (Maintenance Issues Related To Safety, boeing.com). Flight crews and on-board computers can usually monitor most of the planes interior components and its engines, but routine inspections are usually performed to inspect the planes surface area and other places that arent monitored by computers. Several times a day the airline personnel perform walk around checks in which they look for leakage of fluids and problems with surface area of the plane. These problems include dents and cracks. Every three to five days the planes lighting, landing gear, fluid levels, and exterior controls, and the flaps...

The 4,000 Year Old History of Locks

The 4,000 Year Old History of Locks Archeologists found the oldest known lock in the Khorsabad palace ruins near Nineveh. The lock was estimated to be 4,000 years old. It was a forerunner to a pin tumbler type of lock, and a common Egyptian lock for the time. This lock worked using a large wooden bolt to secure a door, which had a slot with several holes in its upper surface. The holes were filled with wooden pegs that prevented the bolt from being opened. The  warded lock  was also present from early times and remains the most recognizable lock and key design in the Western world. The first all-metal locks appeared between the years 870 and 900, and are attributed to the English. Affluent Romans often kept their valuables in secure boxes within their households and wore the keys as rings on their fingers.   During the period of the 18th and 19th centuries - in part to the onset of the Industrial Revolution - many technical developments were made in the locking mechanisms that added to the security of common locking devices. It was during this period that America changed from importing door hardware to manufacturing and even exporting some. The earliest patent for a double-acting pin tumbler  lock  was granted to American physician Abraham O. Stansbury in England in 1805, but the modern version, still in use today, was invented by American Linus Yale, Sr. in 1848. But, other famous locksmiths patented their lock designed before and after Linus. Robert Barron   The first serious attempt to improve the security of the lock was made in 1778 in England. Robert Barron  patented a double-acting tumbler lock. Joseph Bramah   Joseph Bramah patented the safety lock in 1784. Bramahs lock was considered unpickable. The inventor went on to create a Hydrostatic Machine, a beer-pump, the four-cock, a quill-sharpener, a working planer, and more. James Sargent   In 1857, James Sargent invented the worlds first successful key-changeable combination lock. His lock became popular with safe manufacturers and the United States Treasury Department. In 1873, Sargent patented a time lock mechanism that became the prototype of those being used in contemporary bank vaults. Samuel Segal   Mr. Samuel Segal (former New York City policeman) invented the first jimmy proof locks in 1916. Segal holds over twenty-five patents. Harry Soref   Soref founded the Master Lock Company in 1921 and patented an improved padlock. In April 1924, he received a patent (U.S #1,490,987) for his new lock casing. Soref made a padlock that was both strong and cheap using a case constructed out of layers of metal, like the doors of a bank vault. He designed his padlock using laminated steel. Linus Yale Sr.   Linus Yale invented a pin-tumbler lock in 1848. His son improved upon his lock using a smaller, flat key with serrated edges that is the basis of ​the  modern pin-tumbler locks. Linus Yale Jr. (1821-1868)   American, Linus Yale Jr. was a mechanical engineer and lock manufacturer who patented a cylinder pin-tumbler lock in 1861. Yale invented the modern combination lock in 1862.
