Helicopters are capable of flying with no more than a few feet of clearance below the helicopter's skids or wheels. Fast jets are more constrained and at a typical low-flying speed of 450 knots (830 km/h), 200 feet (61 m) is not unusual and 50 feet (15 m) is possible in relatively flat terrain.
False visual reference illusions may cause the pilot to orient the aircraft in relation to a false horizon; these illusions can be caused by flying over a banked cloud, night flying over featureless terrain with ground lights that are indistinguishable from a dark sky with stars, or night flying over a featureless terrain with a clearly defined ...

Low-flying, high-speed military aircraft produce especially loud aerodynamic noise. The shape of the nose, windshield or canopy of an aircraft affects the sound produced. Much of the noise of a propeller aircraft is of aerodynamic origin due to the flow of air around the blades. The helicopter main and tail rotors also give rise to aerodynamic ...
The fighter aircraft and helicopter responded to a civilian aircraft at 2:25 p.m. Saturday and escorted it to the ground. During the event, the aircraft dispensed flares in an attempt to draw ...
All of the reports related to a large object flying at a low altitude. The craft was flat and triangular, with lights underneath. This giant craft did not make a sound as it slowly moved across the landscape of Belgium. The Belgian UFO Wave of 1989–1992 – A Neglected Hypothesis discusses some sightings that helicopters can explain. Most ...
