"MAYDAY! Mayday! Mayday!" The call over the radio that tells the life-threatening emergencies and ask for help quickly. Does Mayday call it effective? In 2008, the U.S. Coast Guard conducted more than 24,000 rescue mission. They save an average of 4910 persons 13 persons per day-and-helping more than 31,000 people at risk.However, why people use the term "Mayday"? And, before there is a radio transmitter, how the ships are in danger of sending a signal for help?
Methods Beginning to Ask for Help
In 1588, the ship Santa Maria de la Rosa of Spain Fleet fired a gun as a signal for help when it swayed a great storm. The boat sank and no one was reported safe. In other cases, the ancient sailors raise the flag as a signal for help. Even now, a white flag with red diagonal cross is stuck on the ship recognized internationally as a signal for help.
The sailors in the 1760's started to learn to use a visual code system called semafor. In this system, a sender of the signal with a flag in his hands mimic the motion of the clock. Each position of "time" which he hinted interpret certain letters or numbers.
However, flags, cannon fire, and visual signals are only effective if the other party close enough to be able to see or hear a message asking for help that. Often times, the crew of a ship in danger do not have much hope that relief will come. How can the situation be improved?
Alerts Request More Effective Aid
There is a major advancement in the field of communication technology in the 1840s. Samuel Morse designed a code that allows the operator to send messages via telegraph wires by using the transmitter is operated manually. During the operator presses the button, the receiver can detect the electrical impulses. Morse determine the particular combination of short and long sounds, or dots and dashes, for each letter and number.
While Morse code is used at sea, the sailors emit bright light instead of sound that is sent by a telegraph operator. The sender emit signal light short-rays symbolize the dots and lines denote the long rays. Furthermore, sending a signal to start using a typical simple message asking for help, yanng consists of three dots, three lines, and three points again, which depict the letters SOS.
Thankfully, the signal for help to grow in terms of range and distance. Guglielmo Marconi sends first radio signals across the Atlantic in 1901. Thus, the SOS message can be sent by using radio waves, no longer with light. However, radio operators have not been able to voice messages asking for help. Call "Mayday! Mayday! Mayday!" not yet born.
Finally people can hear the voice over the airwaves in 1906 when Reginald Fesseden broadcast lectures and music. The sailors who had heard radio broadcasts from a distance of 80 kilometers. in 1915, many more who listen to a sermon that was broadcast live from Arlington, Virginia, USA, to the Eiffel Tower in Paris, France-a distance of more than 14,000 miles! And, imagine the delight of the sailors on American ships in 1922 when the first radio conversation took place between their ships, which are more than 600 miles at sea, with beaches Deal Beach, New Jersey, USA.
Ask Appeals uniform rocks
In the 1920s and 1930s, the conversation over the radio was rife. However, given the crew at sea could be using different language, how the captain could send an emergency message that can be understood internationally? Convention on International Radio telegraph provide a solution in 1927 by adopting a "Mayday" as an international emergency appeal .*
We can be thankful that more and better communication. For example, radar and global positioning system (GPS) has replaced the cannon and flag signals. In addition, the radio became standard equipment, and rescue agencies monitoring the air waves and is always on full alert. As in the case of boat Nautical Legacy, no matter where or when emergencies arise call "Mayday! Mayday! Mayday!" likely to be heard. Unlike past generations who do not have much hope to be saved when in danger at sea, you can expect with confidence that help will come.
* "Mayday" (pronounced meydey) must be repeated three times to clear the point and not confused with other words.
