Aviation includes the activities surrounding mechanical flight and the aircraft industry. Aircraft includes fixed-wing and rotary-wing types, morphable wings, wing-less lifting bodies, as well as lighter-than-air craft such as hot air balloons and airships.
Aviation began in the 18th century with the development of the hot air balloon, an apparatus capable of atmospheric displacement through buoyancy. Some of the most significant advancements in aviation technology came with the controlled gliding flying of Otto Lilienthal in 1896; then a large step in significance came with the construction of the first powered airplane by the Wright brothers in the early 1900s. Since that time, aviation has been technologically revolutionized by the introduction of the jet which permitted a major form of transport throughout the world. (Full article...)

A hot air balloon consists of a bag called the envelope that is capable of containing heated air. Suspended beneath is the gondola or wicker basket (in some long-distance or high-altitude balloons, a capsule) which carries the passengers and a source of heat. The heated air inside the envelope makes it buoyant since it has a lower density than the relatively cold air outside the envelope. Unlike gas balloons, the envelope does not have to be sealed at the bottom since the air near the bottom of the envelope is at the same pressure as the surrounding air. In today's sport balloons the envelope is generally made from nylon fabric and the mouth of the balloon (closest to the burner flame) is made from fire resistant material such as Nomex.
Recently, balloon envelopes have been made in all kinds of shapes, such as hot dogs, rocket ships, and the shapes of commercial products. Hot air balloons that can be propelled through the air rather than just being pushed along by the wind are known as airships or, more specifically, thermal airships. (Full article...)

Selected Aircraft
The Embraer ERJ-145 is a regional jet produced by Embraer, a Brazilian aerospace company. The ERJ 145 is the largest of a family of airliners, which also includes the ERJ 135, ERJ 140, and Legacy. All aircraft in the series are powered by two turbofan engines. It is one of the most popular regional jet families in the world with primary competition coming from the Canadair Regional Jet.
The first flight of the ERJ 145 was on August 11, 1995, with the first delivery in December 1996 to ExpressJet Airlines (then the regional division of Continental Airlines). ExpressJet is the largest operator of the ERJ 145, with 270 of the nearly 1000 ERJ 145s in service. The second largest operator is American Eagle, with 206 ERJ 145 aircraft. Chautauqua Airlines also operates 95 ERJ 145s through its alliances with American Connection, Delta Connection, US Airways Express and United Express. By some accounts, the ERJ 145 has a cost of ownership of about $2,500,000 per year.
