#### Transcript of Into The Sky by Jaqui and Gary

by Jaqui and Gary Into The Sky The Four Forces of Flight The four forces of flight are Thrust, Lift, Drag, and Weight (gravity). Jet Diagram This is a basic diagram of a jet. A jet is faster than an airplane because a jet is
more aerodynamic and it's lighter.

The world's slowest aircraft, the Helios, goes at the speed of most bikes!!

The helios uses Solar Power to fly, and can fly higher then any other plane! Basic Facts II The world's fastest aircraft is the X-15, this aircraft can go up to 4,519 MPH!

The X-15 was built by NASA.

The X-15 actually powered the age of space travel. Basic Facts III On the next frame, you'll see an image of a military jet, which is used in the airforce.

Now For the Facts:
The longest airplane is the Boeing 747-8 at 76.3 meters long!!

The world's shortest airplane flight is a 1.7 jump between 2 Orkney Islands, North of Scotland. How they Help us Airplanes help us today by getting us to places that are very far away very quickly. Airplanes and How They Work Lift Thrust Weight (Gravity) Drag A jet is a type of airplane that can travel at very high speeds. The fastest jet, the X-15, holds the record of traveling nearly 10 times the speed of sound. That's 4,519 MPH. This is the X-15. Thrust is one of the four forces of flight. The engine turns the propeller which builds speed, pulling the plane forward. Drag is the third force of flight. The shape of the plane slows down its forward motion. If the plane is aerodynamic, it will be able to aviate or fly faster. Lift is another force of flight. Air flowing over the wings and the angle of the wings cause the plane to fly. Lift is explained by Bernoulli's Principle. Weight, or gravity, holds the plane down, allowing it to land and dive. Basic Facts I This was Airplanes and How they work
By Jaqui and Gary The End The lower pressure on a planes top wing is caused by the speed of the air over the wing.
The higher pressure below the wing allows the plane to move upwards.
