over 1300 feet and it lasted 12 to 15 seconds
A plane with no engine is a glider. They use the air currents to stay aloft.
A glider is a light engineless aircraft designed to glide after being towed aloft or launched from a catapult. A glider is also a species of small possum, native to Australia. As its name suggests, it is capable of gliding through the air.
There have been many attempts over the years to break the barriers of throwing a paper plane for the longest time aloft. Ken Blackburn held this Guinness World Record for 13 years (1983-1996) and had regained the record on October 1998 by keeping his paper plane aloft for 27.6 seconds (indoors). This was confirmed by Guinness officials and a CNN report.[2] The paper plane that Blackburn used in this record breaking attempt was a "glider".
They ride in "thermals," updrafts of air.
If you are speaking of a paper glider, obviously you want wings that are large for maximum lift. Many record setting paper planes are made using a square shaped wing that allows the wing to have maximum surface area to maintain lift but which is not flimsy, so as the plane's stability in flight is maintained. There are two sites below worth your consideration. The first is a brief instructional on making a highly effective paper glider. The second is the homepage of Dr. Ken Blackburn who holds the world record for time aloft by a paper airplane. He offers several patterns for public use.
A glider is an aircraft with no engine. They are usually launched by being towed aloft by airplanes and are then released.
It is thrust that is the number one concern regarding the tow plane. In an aerotow of a glider, the towing aircraft must drag both itself and the glider aloft. Both ships have "nominal" lift, but it will be the thrust of the towplane that will be critical. Should an advertising sign be wanted aloft, then the towplane will simply have to "muscle" it into the sky. And it takes thrust to do that.
If an airplanes engines fail in flight, the plane can glide for a distance ( depending on it's altitude ), but gravity will eventually bring it down.While most manned airplanes have engines,there are a variety of airplanes that are designed to fly without an engine:sailplane, hang glider, paraglider.Such aircraft can theoretically stay aloft indefinitely in several ways:* towed by a ground vehicle or a powered aircraft* tethered to the ground, with wind (like a kite)* taking advantage of updrafts and ridge lift to gain altitude
Less than a mile.
Seven to eight hours depending on winds aloft.
The plane was flying aloft.
Aloft is an antonym for below or down.
