Worlds first Solar Powered Plane On 8 July 2010, Solar Impulse 1 achieved the world's first manned 26-hour solar-powered flight. The airplane was flown by Borschberg, and took off at 6:51 a.m. Central European Summer Time on 7 July from Payerne Air Base, Switzerland. After the 8 world records set by the Solar Impulse prototype, when it became the first solar airplane ever to fly through the night, between two continents, and across the United States, Bertrand Piccard and André Borschberg accomplished the ultimate phase of the adventure. Solar Impulse II has completed the first solar-powered flight around the world. A solar-powered airplane has circled the globe for the first time, without using any fuel. The Solar Impulse 2 landed in Abu Dhabi more than 16 months after it first took off. It flies at a maximum speed of140 km/h. Dust and rocks can damage them quite a bit and decrease performance. The Solar Impulse 2 will end up costing approximately $170 million, funded mostl...

Stealth Aircraft Stealth aircraft are designed to avoid detection using a variety of technologies that reduce reflection/emission of radar, infrared, visible light, radio frequency spectrum, and audio, collectively known as stealth technology. The most stealth aircraft is the US built Lockheed Martin and Northrop Grumman produced aircrafts F-22 Raptor, F-35 Lighting II and the B-2 Spirit bomber. U.S is the only country which has developed and deployed stealth aircrafts. The goal of stealth technology is to make an airplane invisible to radar.  The airplane can be shaped so that any radar signals it reflects are reflected away from the radar equipment. The airplane can be covered in materials that absorb radar signals. A stealth bomber is The 'flying wing' shaped Stealth Bomber is a unique aircraft that's designed to make it as invisible as possible. As a result, the B-2's thermal signature is kept to the bare minimum, making it harder for thermal sensors to de...

An artificial island is an island constructed by man rather than created by natural means. They are constructed by expanding the existing islets and by construction on existing reefs or merging some natural islets into a bigger island. Artificial islands are usually constructed by land reclamation. On the coast of Dubai in the United Arab Emirates, some of the world's largest artificial islands are under construction. These include Palm Jumeirah, Palm Jebel Ali, Deira Islands, and The World islands. An artificial island or man-made island is an island that has been constructed by people rather than formed by natural means. Artificial islands may vary in size from small islets reclaimed solely to support a single pillar of a building or structure, to those that support entire communities and cities. Spanning an area of 970 square kilometers, "Holland's Flevopolder" is the largest artificial island in the world. "Palm Jumeirah" in Dubai, one of the lar...

Largest Military Aircraft The AN-124 Ruslan was developed by Antonov, is the world's biggest military transport aircraft thanks to its giant take-off weight of 392t. Lockheed C-5 Galaxy. Currently the An-124 is the world's largest production military aircraft. The C-5 Galaxy is 247 feet long, the wingspan is 222 feet and its 65 feet tall. The C-17 is 174 ft long, the wingspan is 170 ft and its 55 ft tall. Antonov An-225 Mriya is the largest aircraft by weight, length and wingspan.

Illusion, a misrepresentation of a real sensory stimulus it is, an interpretation that contradicts objective reality as defined by general agreement. For example, a child who perceives tree branches at night as if they are goblins may be said to be having an illusion. Illusions distort one's senses. Most illusions tend to deceive the eyes, ears and skin, while there are some illusions that may distort perception due to changes in internal body structures. The three main types of illusion include optical illusions, auditory illusions, and tactile illusions. Epicharmus and Protagorus invented optical illusions in 450 B.C.An illusion occurs when the auditory component of one sound is paired with the visual component of another sound, leading to the perception of a third sound.
