The Absence of Sonic Booms 
Concerning Interstellar Craft as they Engage Earth's Atmosphere during 
Supersonic Movement
 
   The absence of sonic booms was recently used as a reason to debunk the first 
group of unidentified craft coined “flying saucer” in June 1947 in the state of 
Washington seen by a lone pilot in a single engine plane on the History Channel 
(Dec 2007). The point, no one on the ground heard the sonic boom of the several 
craft moving approximately 1700 mph backing the story of the pilot, so how was 
this possible?
   Mankind assumes all aircraft made on Earth moving above the speed of sound perform the same 
as interstellar craft. They would, if they were using principles of lift and 
flight developed on Earth. As we know, aircraft in general, depend a pressure 
differentials between the top and lower portion of the wing due the its shape 
forcing air to move over a larger cross sectional area than below. This imbalance creates a low 
pressure above the wing to that below it, if the total force differential 
between the upper and lower portions exceeds the mass of the 
plane, the plane exhibits lift. For aircraft that approaches the speed of sound 
in our atmosphere, pressure waves begin to build and then 
compresses into one wave in front of the air as velocity proceeds to exceed the velocity of sound in 
the Earth's atmosphere.
   Interstellar craft rely on managing the local  
gravitational field on a micro second to micro second status for real time 
maintenance of a static position above a cosmic mass. Primary concern of the 
craft is to evaluate the gravitational field and any source of anomalies from 
an outside mass in 
conjunction with neutralizing natural planetary forces related to the movement of 
atmosphere. The field is not maintained in a steady state, but morphs by 
reforming itself to adapt to a changing environment from time interval to time interval. 
While interstellar craft are on the move, by nullifying gravity through 
engagement of the repulsion force, which equalizes force on a 
mass due to gravitational subatomic particle flow. There is no need to alter the 
surface exterior of the craft to negotiate flight within  a planetary 
atmosphere. This allows a symmetry of air flow about the space craft instead of a 
build up of air molecules that creates pressure wave along the frontal edge of 
the craft as the speed of sound is exceeded.
   As the craft separates the 
atmosphere around the craft and there is an equal pressurized of air flow above 
and below. Thus minimizing 
any primary wave build up along the frontal edge of engagement of the craft 
within our atmosphere, compression is uniform as the air 
moves about the craft. This compression of stored potential energy causes 
the spring back of the atmosphere somewhat equally against the symmetrical shape 
of the craft creating little chance of a air pressure void, thus causing a rush 
in and its subsequent clap. As the craft slices through the atmosphere of most planets, 
including our own, it 
creates no sonic boom as the formation of pressure waves created by moving 
faster than the speed of sound are absent. Thus, what is needed to produced the sonic boom 
never occurs. No matter how fast the craft moves in our atmosphere.
