Bomber
A bomber is a military combat aircraft designed to attack ground and naval targets by dropping air-to-ground weaponry (such as bombs), launching aerial torpedo, torpedoes, or deploying air-launched cruise missiles. The first use of bombs dropped from an aircraft occurred in the Italo-Turkish War, with the first major deployments coming in the World War I, First World War and World War II, Second World War by all major airforces causing devastating damage to cities, towns, and rural areas. The first purpose built bombers were the Italy, Italian Caproni Ca 30 and United Kingdom, British Bristol T.B.8, both of 1913. Some bombers were decorated with nose art or victory markings. There are two major classifications of bomber: strategic and tactical. Strategic bombing is done by heavy bombers primarily designed for long-range bombing missions against strategic targets to diminish the enemy's ability to wage war by limiting access to resources through crippling infrastructure or reduci ...

Aircrew
Aircrew, also called flight crew, are personnel who operate an aircraft while in flight. The composition of a flight's crew depends on the type of aircraft, plus the flight's duration and purpose. Commercial aviation Flight deck positions In commercial aviation, the aircrew are called ''flight crew''. Some flight crew position names are derived from nautical terms and indicate a rank or command structure similar to that on ocean-going vessels, allowing for quick executive decision making during normal operations or emergency situations. Historical flightdeck positions include: * Captain, the pilot highest-ranking member or members of a flight crew. * First officer (FO, also called a co-pilot), another pilot who is normally seated to the right of the captain. (On helicopters, an FO is normally seated to the left of the captain, who occupies the right-hand seat).Smith, PatrickPatrick Smith's Ask The Pilot: When a Pilot Dies in Flight AskThePilot.com website, 2013, whic ...

Consolidated B-24 Liberator
The Consolidated B-24 Liberator is an American heavy bomber, designed by Consolidated Aircraft of San Diego, California. It was known within the company as the Model 32, and some initial production aircraft were laid down as export models designated as various LB-30s, in the Land Bomber design category. At its inception, the B-24 was a modern design featuring a highly efficient shoulder-mounted, high aspect ratio Davis wing. The wing gave the Liberator a high cruise speed, long range and the ability to carry a heavy bomb load. Early RAF Liberators were the first aircraft to cross the Atlantic Ocean as a matter of routine. In comparison with its contemporaries, the B-24 was relatively difficult to fly and had poor low-speed performance; it also had a lower ceiling and was less robust than the Boeing B-17 Flying Fortress. While aircrews tended to prefer the B-17, General Staff favored the B-24 and procured it in huge numbers for a wide variety of roles. At approximately 18,5 ...
