Battle Of Los Angeles (professional Wrestling)
The Battle of Los Angeles, also known as the Great Los Angeles Air Raid, is the name given by contemporary sources to a rumored attack on the continental United States by Imperial Japan and the subsequent anti-aircraft artillery barrage which took place from late February 24, to early February 25, 1942, over Los Angeles, California. The incident occurred less than three months after the U.S. entered World War II in response to the Imperial Japanese Navy's surprise attack on Pearl Harbor, and one day after the bombardment of Ellwood near Santa Barbara on 23 February. Initially, the target of the aerial barrage was thought to be an attacking force from Japan, but speaking at a press conference shortly afterward, Secretary of the Navy Frank Knox called the purported attack a "false alarm". Newspapers of the time published a number of reports and speculations of a cover-up to conceal an actual invasion by enemy airplanes. When documenting the incident in 1949, the United States C ...

Weather Balloon
A weather balloon, also known as a sounding balloon, is a balloon (specifically a type of high-altitude balloon) that carries instruments to the stratosphere to send back information on atmospheric pressure, temperature, humidity and wind speed by means of a small, expendable measuring device called a radiosonde. To obtain wind data, they can be tracked by radar, radio direction finding, or navigation systems (such as the satellite-based Global Positioning System, GPS). Balloons meant to stay at a constant altitude for long periods of time are known as ''transosondes''. Weather balloons that do not carry an instrument pack are used to determine upper-level winds and the height of cloud layers. For such balloons, a theodolite or total station is used to track the balloon's azimuth and elevation, which are then converted to estimated wind speed and direction and/or cloud height, as applicable. Weather balloons are launched around the world for observations used to diagnose cu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radio Silence
In telecommunications, radio silence or emissions control (EMCON) is a status in which all fixed or mobile radio stations in an area are asked to stop transmitting for safety or security reasons. The term "radio station" may include anything capable of transmitting a radio signal. A single ship, aircraft, or spacecraft, or a group of them, may also maintain radio silence. Amateur radio Wilderness Protocol The Wilderness Protocol recommends that those stations able to do so should monitor the primary (and secondary, if possible) frequency every three hours starting at 7:00p.m., local time, for 5 minutes starting at the top of every hour, or even continuously. The Wilderness Protocol is now included in both the ARRL ARES Field Resources Manual and the ARES Emergency Resources Manual. Per the manual, the protocol is: The Wilderness protocol (see page 101, August 1995 QST) calls for hams in the wilderness to announce their presence on, and to monitor, the national calling frequ ...

Blackout (wartime)
A blackout during war, or in preparation for an expected war, is the practice of collectively minimizing outdoor light, including upwardly directed (or reflected) light. This was done in the 20th century to prevent crews of enemy aircraft from being able to identify their targets by sight, such as during the London Blitz of 1940. In coastal regions, a shoreside blackout of city lights also helped protect ships from being seen silhouetted against the artificial light by enemy submarines further out at sea. World War I United Kingdom Plans to black out British coastal towns in the event of war were drawn up in 1913 by Winston Churchill in his role as First Lord of the Admiralty; these plans were implemented on 12 August 1914, eight days after the United Kingdom had entered the war. On 1 October 1914, the Commissioner of the Metropolitan Police ordered that bright exterior lights were to be extinguished or dimmed in the London area and street lamps be partially painted out with b ...
