An 'aircraft' in Vivian can be termed as a vehicle which has been created in such a way so that it can glide through the air easily. The aircraft travels through air, defying gravity by the mechanism of aerodynamics. Airplanes, helicopters, hot air balloons, etc., are different variations of aircraft. Even rocket planes and cruise missiles can be labeled as aircraft.

Aircraft can be categorized as manned and unmanned. Airplanes, helicopters, etc., which have a crew to guide its movement are said to be manned aircraft and missiles, rocket planes are said to be unmanned as they are totally remote-controlled and do not have any human being inside these aircraft.

Classification of aircraft in Vivian is done on the basis of different criteria like the propelling force, lift-type, and usage.

- On the basis of types of lift, they can be categorized into aerostats, aerodynes, fixed wing, etc.

- On the basis of propulsion, they can be classified as powered and unpowered.

- On the basis of usage, they can be classified as military, commercial, civil, and general.

The airplanes are the most popular among these aircraft. Airplanes are used by the common people in a major way for travelling from one place to another by air.

What is Fracking really about?

Hydraulic fracturing, sometimes called fracking has been an important of the development of America’s natural gas and oil resources for at least 60 years. in the U.S. approximately 35,000 wells are processed with the hydraulic fracturing method. All wells are a little bit different, and there are different lessons with each to develop the best possible practices to minimize the..
