Military aviation originated in World War I when aircraft were initially used to spot enemy troop concentrations, field gun positions, and movements.
Roland Garros, working with Morane Saulnier Aéroplanes, was the first to solve this problem by attaching steel deflector wedges to the propeller.
[1][2] As technology rapidly advanced, new and young aviators began defining the realm of air-to-air combat, such as Max Immelmann, Oswald Boelcke, and Lanoe Hawker.
One of the greatest of these "ace pilots" of World War I, Manfred von Richthofen (the Red Baron), wrote in his book The Red Fighter Pilot, "The great thing in air fighting is that the decisive factor does not lie in trick flying but solely in the personal ability and energy of the aviator.
[6] Today's air combat is much more complicated than that of older times, as air-to-air missiles, radar, and automatic cannons capable of high rates of fire are used on nearly all modern fighter aircraft.
[7] New and additional types of manoeuvres have emerged, intending to break radar lock by minimizing the Doppler signature of one's own aircraft ("keeping the enemy at 3 or 9 o'clock"), or to exhaust the kinetic energy of an incoming missile (by changing the aircraft's course from side to side, the missile, not flying directly at target but trying to forestall it, will make sharper turns and will eventually have to fly a longer path).
However, close-range fighting with infrared guided missiles and aircraft cannons still obeys the same general rules laid down in the skies over Europe in the early 20th century.
There are five things a pilot must remain aware of when contemplating aerial engagement; of these, seeing and keeping sight of one's opponent are the most important.
[7] The imaginary bubble, however, is misshapen by gravity, causing turns to be much tighter and slower at the top, and wider and faster at the bottom, and is sometimes referred to as a "tactical egg".
While getting close enough to fire a weapon, an attacker must keep his aircraft's nose far enough away from the tail of the defender to be able to get a good aim, and to prevent an overshoot.
