What is ZERO-G ?
Weightlessness,
or an absence of weight, is an absence of stress and strain resulting from
externally applied mechanical contact-forces, typically normal forces (from
floors, seats, beds, scales, etc.). Counter intuitively, a uniform gravitational
field does not by itself cause stress or strain, and a body in free fall in
such an environment experiences no g-force acceleration and feels weightless.
This is also termed zero-g, where the term is more correctly understood as
meaning "zero g-force."

Passengers
on a zero gravity flight (and astronauts on a spacecraft) appear to be floating
around inside the plane but they are in fact falling at the same rate as the
aircraft.
What happens on a zero gravity
flight?
A
zero gravity flight follows a parabolic flight path, which involves three
stages. The first part of the trajectory sees the plane - which is specially
customised, and boasts a padded interior to avoid injury - reach an altitude of
24,000 feet, at which point the nose of the plane is lifted upward to an angle
of about 45 degrees until the plane reaches around 32,000 feet.
At
this point, the nose of the plane is lowered to a level position during which
passengers experience a sense of weightlessness for the next 20-30 seconds.
After these few seconds, the nose of the plane is tilted back downward 45
degrees to complete the third and final stage, before it levels off to a normal
altitude.
Passengers
experience a pull of nearly twice that of gravity (1.8 Gs) during the downward
trajectory, at the bottom of the path, as well as the upward climb of the
flight, which takes around 65 seconds to complete.
As
well as the experience of floating, passengers will experience nausea due to
motion sickness during the journey - which prompted such flights' nickname of
the “vomit comet”. During NASA’s former Reduced Gravity Programmed, one third
of the participants were said to have become “violently ill, the next third
moderately ill, and the final third not at all," according to John Yaniec,
the former director of the programmer.
The
main cause of the air sickness is anxiety, according to Yaniec, who said being
in a state of zero gravity “is out of the ordinary” and “it’s a bit of the fear
of the unknown too”.
You want to get on to one of same
plane?
If
you want get on to same plane, there is company called NOVASPACE is providing
same service for general public at cost of $5000 along with another 39 passengers.
