Expert said that an aluminum is a silvery white and ductile member of the boron group of chemical elements. It has the symbol Al; its atomic number is 13. It is not soluble in water under normal circumstances. Aluminum is the most abundant metal in the Earth’s crust, and the third most abundant element therein, after oxygen and silicon. It makes up about 8% by weight of the Earth’s solid surface. Aluminium is too reactive chemically to occur in nature as a free metal. Instead, it is found combined in over 270 different minerals. The chief source of aluminium is bauxite ore. Aluminium is remarkable for its ability to resist corrosion due to the phenomenon of passivation and for the metal’s low density. Structural components made from aluminium and its alloys are vital to the aerospace industry and very important in other areas of transportation and building. Its reactive nature makes it useful as a catalyst or additive in chemical mixtures, including being used in ammonium nitrate explosives to enhance blast power. It is being use now around the world by several expert.

According to expert an aircraft is a vehicle which is able to fly by being supported by the air, or in general, the atmosphere of a planet. An aircraft counters the force of gravity by using either static lift as with balloons, blimps and dirigibles or by using the dynamic lift of an airfoil as with vehicles that plane the air with wings in a straight manner, such as airplanes and gliders, or vehicles that generate lift with wings in a rotary manner, such as helicopters or gyrocopters. There are military aircraft, this aircraft are aircraft designed to destroy enemy equipment using its own armament. There are also non-combat which are aircraft not designed for combat as their primary function, but may carry weapons for self-defense. Mainly operating in support roles.
There are also aircraft use as for civil aircraft and commercial aircraft. In general aviation is a catch-all covering other kinds of private and commercial use, and involving a wide range of aircraft types such as business jets, trainers, homebuilt, aerobatic types, racers, gliders, war birds, firefighters, medical transports, and cargo transports, to name a few. The vast majority of aircraft today are general aviation types.
