Taking a flight creates physical and emotional changes in us, something that is now being more extensively researched. Air travel can change our mood, make us emotionally weak (more crying) or sad, and even change how our senses work.
The factors responsible for this phenomenon are the high altitude, the reduced air pressure, inadequate oxygen going in the brain and overall anxiety associated with flying.

Planes can fly quite easily without engines, as gliders (planes without engines), paper planes, and gliding birds show us.
A plane's engine is designed to move the plane for...
A plane throws the air down behind it by making a spinning vortex - a kind of mini-tornado.
Most of the vortex is moving downward, but not all. There's a huge draft of air moving down in the center, but the air also swirls upward on either side of the wingtips, reducing lift.
If you're in a plane and steering around a circle, the centripetal force comes from leaning into a curve, just like a cyclist leans into a bend.
Steering involves banking, where the plane tilts to one side causing the one wing to dip. The plane's overall lift is tilted at an angle, making some of the lift act sideways. This sideways part of the lift provides the centripetal force that makes the plane go around in a circle. But turning the plane in a circle will make it lose lift and altitude, unless the pilot uses the elevators to increase the angle of attack to cause lift again.

Research has found that willing exposure to that which scares us can provide a counterbalance to life's stresses:

Newton’s Third Law Of Motion, which states that every action has an equal and opposite reaction is the heart of rocket science.
The basics of rocket science are not that complicate...
The thrust required for an object to overcome Earth’s gravity and atmospheric resistance and move towards space is called escape velocity. Besides Earth, the gravitational forces that can affect the object are those coming from the sun, moon and even other planets.
Apart from space vehicles and the military, rockets are used in life-saving rescue flares and fireworks, and even the ejector seats in military planes.
