It is what makes us go, through the air anyway. Thrust is a force created by the acceleration of matter, like air. This is an application of Newton's Second Law of Motion expressed as Force = Mass x Acceleration. There are several ways to accomplish this, some better than others, but the goal is to get us from one place to another as quickly and efficiently as possible.

Today's Random Fact:

A "pound of thrust" is equal to a force able to accelerate 1 pound of material 32 feet per second per second (32 feet per second per second happens to be equivalent to the acceleration provided by gravity). Therefore, if you have a jet engine capable of producing 1 pound of thrust, it could hold 1 pound of material suspended in the air if the jet were pointed straight down.

Bonus Fact:

According to the Guinness Book of Records, the General Electric GE90 is the most powerful jet engine in the world. Normally generating over 122,000 pounds of thrust, the GE90 generated a record 127,900 pounds of thrust as part of a one-hour, triple-red-line engine stress test. The space shuttle's main engines, on the other hand, produce about 418,000 pounds of thrust each at liftoff.
