Aurel Vlaicu (November 19, 1882 – September 13, 1913) was a Romanian engineer, inventor, airplane constructor and early pilot.

Aurel Vlaicu was born in Binţinţi, Transylvania. He attended Calvinist High School in Orăştie and took his Baccalaureate in Sibiu in 1902. He furthered his studies at Technical University of Budapest and Technische Hochschule München in Germany, earning his engineer's diploma in 1907.
After working at Opel car factory in Rüsselsheim, he returned to Binţinţi and built a glider he flew in the summer of 1909. Later that year, he moved to Bucharest, in the Kingdom of Romania, where he began the construction of Vlaicu Nr. I airplane; it flew for the first time on June 17, 1910.
With his Vlaicu Nr. II model, built in 1911, Aurel Vlaicu won several prizes summing 7,500 Austro-Hungarian krone (for precise landing, projectile throwing and tight flying around a pole) in 1912 at Aspern Air Show near Vienna, where he competed against 42 other aviators of the day, including Roland Garros.
Aurel Vlaicu died in 1913 near Câmpina while attempting to cross in flight the Carpathian Mountains in his aged Vlaicu II airplane. He is buried at the Bellu cemetery, in Bucharest.

Eagles are members of the bird family Accipitridae, and belong to several genera which are not necessarily closely related to each other. Most of the more than 61 species occur in Eurasia and Africa. Outside this area, just two species (the Bald and Golden Eagles) can be found in the United States and Canada, nine more in Central and South America, and three in Australia.

Eagles are large, powerfully built birds of prey, with a heavy head and beak. Even the smallest eagles, like the Booted Eagle, have relatively longer and more evenly broad wings, and more direct, faster flight. Most eagles are larger than any other raptors apart from some vultures. Species named as eagles range in size from the South Nicobar Serpent Eagle, at 500 g and 40 cm , to the 6.7 kg Steller's Sea Eagle and the 100 cm Philippine Eagle. Like all birds of prey, eagles have very large hooked beaks for tearing flesh from their prey, strong muscular legs, and powerful talons. The beak is typically heavier than most other birds of prey. They also have extremely keen eyesight which enables them to spot potential prey from a very long distance. This keen eyesight is primarily contributed by their extremely large pupils which ensure minimal diffraction (scattering) of the incoming light. The female of all species of eagle known are larger than the male.
Eagles normally build their nests, called eyries, in tall trees or on high cliffs. Many species lay two eggs, but the older, larger chick frequently kills its younger sibling once it has hatched. The dominant chick tends to be the female, as they are bigger than the male. The parents take no action to stop the killing.
