| WLW Radio Tower |
On March 22, 1922, Crosley and his Crosley Broadcasting Corporation began broadcasting with the new callsign WLW and 50 watts of power. Crosley was a fanatic about the new broadcasting technology, and continually increased his station's capability. The power went up to 500 watts in September 1922, 1000 watts in May 1924, and in January 1925 WLW was the first broadcasting station at the 5000 watt level. On October 4, 1928, the station increased its power to 50 kilowatts. Again it was the first station at this power level, which still is the maximum power currently allowed for any AM station in the United States.
At 50 kilowatts, WLW was heard easily over a wide area, from New York to Florida. But Crosley still wasn't satisfied. In 1933 he obtained a construction permit from the Federal Radio Commission for a 500 kilowatt superstation, and he spent some $500,000 (at least $17 million in 2010 dollars using a CPI conversion factor of 0.13 building the transmitter and antenna.
It was the first large amplifier used in the United States for public domestic radio broadcasting and was in operation between 1934 and 1939. It was an experimental amplifier and was driven by the radio station's regular 50 kW transmitter. It operated in class C with high-level plate modulation. The amplifier required a dedicated 33 kV electrical substation and a large pond complete with fountains for cooling. It operated with a power input of about 750 kW (plus another 400 kW of audio for the modulator) and its output was 500 kW.
In January 1934 WLW began broadcasting at the 500 kilowatt level late at night under the experimental callsign W8XO. In April 1934 the station was authorized to operate at 500 kilowatts during regular hours under the WLW call letters. On May 2, 1934, President Franklin D. Roosevelt pressed a ceremonial button that officially launched WLW's 500-kilowatt signal. As the first station in the world to broadcast at this strength, WLW received repeated complaints from around the United States and Canada that it was overpowering other stations as far away as Toronto. In December 1934 WLW cut back to 50 kilowatts at night to mitigate the interference, and began construction of three 50 ft. tower antennas to be used to reduce signal strength towards Canada. With these three antennas in place, full-time broadcasting at 500 kilowatts resumed in early 1935. However, WLW was continuing to operate under special temporary authority that had to be renewed every six months, and each renewal brought complaints about interference and undue domination of the market by such a high-power station. The FCC was having second thoughts about permitting extremely wide-area broadcasting versus more locally oriented stations, and in 1938, the US Senate adopted the "Wheeler" resolution, expressing it to be the sense of that body that more stations with power in excess of 50 kilowatts are against the public interest. As a result, in 1939 the 500-kilowatt broadcast authorization was not renewed, bringing an end to the era of the AM radio superstation.Because of the impending war and the possible need for national broadcasting in an emergency, the W8XO experimental license for 500 kilowatts remained in effect until December 29, 1942. In 1962 the Crosley Broadcasting Corporation again applied for a permit to operate at 750 kilowatts, but the FCC denied the application.

Mark Showalter of the SETI Institute discovered S/2004 N 1 in July 2013 when examining Hubble Space Telescope (HST) images of Neptune's ring arcs from 2009 using a technique similar to panning to compensate for orbital motion. On 1 July 2013, after deciding "on a whim" to expand the search area to radii well beyond the rings, he found the "fairly obvious dot" that represented the new moon. He then found the satellite in other archival HST images going back to 2004. Voyager 2, which had observed all of Neptune's other inner satellites, did not detect the moon during its 1989 flyby, due to its dimness.[4] Given that the discovery images have long been available to the public, the moon could have been found by anyone. S/2004 N 1 is the fourteenth known moon of Neptune, and the first Neptunian moon discovery to be announced
The Manhattan Project was a research and development project that produced the first atomic bombs during World War II. It was led by the United States with the support of the United Kingdom and Canada. From 1942 to 1946, the project was under the direction of Major General Leslie Groves of the US Army Corps of Engineers. It began modestly in 1939, but grew to employ more than 130,000 people and cost nearly US$2 billion (the equivalent of about $26 billion now). Although it operated under a tight blanket of security, it was penetrated by Soviet atomic spies. The first device ever detonated was an implosion-type nuclear weapon in the Trinity test (pictured), conducted at New Mexico's Alamogordo Bombing and Gunnery Range on 16 July 1945. Project personnel participated in the Alsos Mission in Europe, and in the bombing of Hiroshima and Nagasaki. After the war the Manhattan Project conducted weapons testing in Operation Crossroads, developed new weapons, established the network of national laboratories, supported medical research into radiology, and laid the foundations for a nuclear navy. It was replaced by the Atomic Energy Commission and the Armed Forces Special Weapons Project in 1947
IN THE LATE 1980'S, IN A DECISION IT PROBABLY REGRETS, THE U.S. PROMPTED NEW ZEALAND TO JOIN A NEW AND HIGHLY SECRET GLOBAL INTELLIGENCE SYSTEM. HAGER'S INVESTIGATION INTO IT AND HIS DISCOVERY OF THE ECHELON DICTIONARY HAS REVEALED ONE OF THE WORLD'S BIGGEST, MOST CLOSELY HELD INTELLIGENCE PROJECTS. THE SYSTEM ALLOWS SPY AGENCIES TO MONITOR MOST OF THE WORLD'S TELEPHONE, E-MAIL, AND TELEX COMMUNICATIONS.

Sallie Gardner at a Gallop is a series of photographs of a galloping horse, the result of a photographic experiment by Eadweard Muybridge on June 15, 1878. Sometimes cited as an early silent film, the series and later experiments like it were precursors to the development of motion pictures. The series consists of 24 photographs shot in rapid succession that were shown on a zoopraxiscope. Muybridge was commissioned by Leland Stanford, the industrialist and horseman, who was interested in gait analysis. The purpose of the shoot was to determine whether a galloping horse ever lifts all four feet completely off the ground during the gait; at this speed, the human eye cannot break down the action.
flies you up and out through the gunfire to the doctors and nurses and safety.And, he kept coming back!! 13 more times!! Until all the wounded were out. No one knew until the mission was over that the Captain had been hit 4 times in the legs and left arm. He took 29 of you and your buddies out that day. Some would not have made it without the Captain and his Huey. Medal of Honor Recipient, Captain Ed Freeman, United States Air Force, died last Wednesday at the age of 70, in Boise , Idaho May God Bless and Rest His Soul.n I bet you didn't hear about this hero's passing, but we've sure seen a whole bunch about Lindsay Lohan, Tiger Woods and the bickering of congress over Health Reform. Medal of Honor Winner Captain Ed Freeman Shame on the media !!!
Lazar claimed to have worked in 1988 and 1989 as a physicist at S4 allegedly located at Papoose Lake southwest of top secret Area 51 near Groom Dry Lake, Nevada. According to Lazar, S4 serves as a hidden military location for the study and research of extraterrestrial spacecraft, or flying saucers using reverse engineering. Lazar says he saw nine different extraterrestrial vehicles there and has provided detailed information on the mode of propulsion and other technical details of a disc-shaped vehicle he called the sport model.
