Perhaps the most famous fighter plane during World War 1 was the Fokker as it was the first to include a synchronized machine gun. [23] [24] [25] Towards the end of the conflict, aircraft carriers were used for the first time, with HMS Furious launching Sopwith Camels in a raid to destroy the Zeppelin hangars at Tønder in 1918.

History of radio. The early history of radio is the history of technology that produces and uses radio instruments that use radio waves. Within the timeline of radio, many people contributed theory and inventions in what became radio. Radio development began as "wireless telegraphy". Later radio history increasingly involves matters of ...
An antenna farm hosting various radio antennas on Sandia Peak near Albuquerque, New Mexico, US. Radio is the technology of communicating using radio waves. [1][2][3] Radio waves are electromagnetic waves of frequency between 3 hertz (Hz) and 300 gigahertz (GHz). They are generated by an electronic device called a transmitter connected to an ...
Audio broadcasting (1915 to 1950s) 1919: First clear transmission of human speech, (on 9XM) after experiments with voice (1918) and music (1917). 1920: Regular wireless broadcasts for entertainment began in Argentina, pioneered by the group around Enrique Telémaco Susini. 1920: Spark-gap telegraphy stopped.
A French ship-to-shore radio station in 1904. The invention of radio communication was preceded by many decades of establishing theoretical underpinnings, discovery and experimental investigation of radio waves, and engineering and technical developments related to their transmission and detection. These developments allowed Guglielmo Marconi ...
Military communications – or "comms" – are activities, equipment, techniques, and tactics used by the military in some of the most hostile areas of the earth and in challenging environments such as battlefields, on land (compare radio in a box), underwater and also in air. Military comms include command, control and communications and ...
Air-to-ground communication was first made possible by the development of two-way aerial telegraphy in 1912, soon followed by two-way radio. By the Second World War, radio had become the chief medium of air-to-ground and air-to-air communication. Since then, transponders have enabled pilots and controllers to identify planes automatically ...
Crystal radios are the simplest type of radio receiver [2] and can be made with a few inexpensive parts, such as a wire for an antenna, a coil of wire, a capacitor, a crystal detector, and earphones (because a crystal set has insufficient power for a loudspeaker). [3]
