Doppler radar has the potential to detect NOE flight, but the incoming aircraft has to be within radar range in the first place, and low flight minimizes this possibility by using hills and mountains to break the line of sight (terrain masking), defeating terrestrial air defense radar and in rough enough terrain also airborne early warning.

As reported in many personal accounts by the pilots in their memoirs, the speed at which the aircraft would actually stall was 24 miles per hour (39 km/h). Either speed making it the slowest aircraft used in WW2 and possibly the slowest conventional warplane of all time. [6] The Antonov An-2 had no published stall speed. At low speeds its ...
An air speed record is the highest airspeed attained by an aircraft of a particular class. The rules for all official aviation records are defined by Fédération Aéronautique Internationale (FAI), [1] which also ratifies any claims. Speed records are divided into a number of classes with sub-divisions.
Stall speed or minimum steady flight speed for which the aircraft is still controllable. [7] [8] [9] V S 0: Stall speed or minimum flight speed in landing configuration. [7] [8] [9] V S 1: Stall speed or minimum steady flight speed for which the aircraft is still controllable in a specific configuration. [7] [8] V S R: Reference stall speed. [7 ...
The affected flights included Virgin Atlantic Flight 22, which departed from Washington Dulles International Airport (IAD) at 10:45 p.m. Saturday and landed in London 45 minutes early due to the ...

Here the speed is displayed both in knots (kn) and miles per hour (mph). The true airspeed (TAS; also KTAS, for knots true airspeed) of an aircraft is the speed of the aircraft relative to the air mass through which it is flying. The true airspeed is important information for accurate navigation of an aircraft.
Ground speed is just a pilot aid to estimate if the flight is on time, behind or ahead of schedule. It is not used for takeoff and landing purposes, since the imperative speed for a flying aircraft always is the speed against the wind. The Machmeter is, on subsonic aircraft, a warning indicator.
