   aircraft spotting or plane spotting is the observation, photographing, and logging of the registration numbers of aircraft, which includes gliders, balloons, airships, helicopters, and microlights. ==history and evolution== aviation enthusiasts may have been watching airplanes and other aircraft ever since they were invented. however, plane spotting was not considered a distinct hobby until the second half of the 20th century. the development of technology and global resources enabled a revolution in spotting. point and shoot cameras, dslrs & walkie talkies significantly changed the hobby. with the help of the internet, websites, such as flightaware, have made it possible for spotters to track and locate specific aircraft from all across the world. websites, such as airliners.net, allow spotters to upload their shots or see pictures of aircraft spotted by other people from all over the world. ==techniques==  when spotting aircraft, observers generally notice the key attributes of an aircraft, such as a distinctive noise from its engine or the number of vapour trails it is leaving. observers assess the size of the aircraft and the number, type and position of its engines. another distinctive attribute is the position of wings relative to the fuselage and the degree to which they are swept rearwards. the wings may be above the fuselage, below it, or fixed at midpoint. the number of wings indicate whether it is a monoplane, biplane, or triplane. the position of the tailplane relative to the fin(s) and the shape of the fin are other attributes. the configuration of the landing gear can be distinctive, as well. other features include the speed, cockpit placement, colour scheme or special equipment that changes the silhouette of the aircraft. taken together these traits will enable the identification of an aircraft. if the observer is familiar with the airfield being used by the aircraft and its normal traffic patterns, he or she is more likely to leap quickly to a decision about the aircraft's identity - they may have seen the same type of aircraft from the same angle many times.
