Torpedo Bomber
A torpedo bomber is a military aircraft designed primarily to attack ships with aerial torpedoes. Torpedo bombers came into existence just before the First World War almost as soon as aircraft were built that were capable of carrying the weight of a torpedo, and remained an important aircraft type until they were rendered obsolete by anti-ship missiles. They were an important element in many famous Second World War battles, notably the British attack at Taranto, the sinking of the German battleship ''Bismarck'', and the Japanese attack on Pearl Harbor. Types Torpedo bombers first appeared immediately prior to the First World War. Generally, they carried torpedoes specifically designed for air launch, which were smaller and lighter than those used by submarines and surface warships. Nonetheless, as an airborne torpedo could weigh as much as , more than twice the bomb load of contemporary single-engined bombers, the aircraft carrying it usually needed to be specially designed ...

Airmail
Airmail (or air mail) is a mail transport service branded and sold on the basis of at least one leg of its journey being by air. Airmail items typically arrive more quickly than surface mail, and usually cost more to send. Airmail may be the only option for sending mail to some destinations, such as overseas, if the mail cannot wait the time it would take to arrive by ship, sometimes weeks. The Universal Postal Union adopted comprehensive rules for airmail at its 1929 Postal Union Congress in London. Since the official language of the Universal Postal Union is French, airmail items worldwide are often marked ''Par avion'', literally: "by airplane". For about the first half century of its existence, transportation of mail via aircraft was usually categorized and sold as a separate service (airmail) from surface mail. Today it is often the case that mail service is categorized and sold according to transit time alone, with mode of transport (land, sea, air) being decided on the ...

Reconnaissance Plane
In military operations, reconnaissance or scouting is the exploration of an area by military forces to obtain information about enemy forces, terrain, and other activities. Examples of reconnaissance include patrolling by troops (skirmishers, long-range reconnaissance patrol, U.S. Army Rangers, cavalry scouts, or military intelligence specialists), ships or submarines, crewed or uncrewed reconnaissance aircraft, satellites, or by setting up observation posts. Espionage is usually considered to be different from reconnaissance, as it is performed by non-uniformed personnel operating behind enemy lines. Often called recce (British, Canadian and Australian English) or recon (American English), the word for this activity has at its root the associated verb ''reconnoitre'' or ''reconnoiter''. Etymology The word from the Middle French ''reconoissance''. Overview Reconnaissance conducted by ground forces includes special reconnaissance, armored reconnaissance, amphibious recon ...

Airport
An airport is an aerodrome with extended facilities, mostly for commercial air transport. Airports usually consists of a landing area, which comprises an aerially accessible open space including at least one operationally active surface such as a runway for a plane to take off and to land or a helipad, and often includes adjacent utility buildings such as control towers, hangars and terminals, to maintain and monitor aircraft. Larger airports may have airport aprons, taxiway bridges, air traffic control centres, passenger facilities such as restaurants and lounges, and emergency services. In some countries, the US in particular, airports also typically have one or more fixed-base operators, serving general aviation. Operating airports is extremely complicated, with a complex system of aircraft support services, passenger services, and aircraft control services contained within the operation. Thus airports can be major employers, as well as important hubs for tourism ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
