Balloon Shaped Like A House From Up

A balloon is a type of aerostat that remains aloft due to its buoyancy. A balloon travels by moving with the wind. It is distinct from an airship, which is a buoyant aircraft that can be propelled through the air in a controlled manner.

The “basket” or capsule that is suspended by cables beneath a balloon and carries people, animals, or automatic equipment (including cameras and telescopes, and flight-control mechanisms) may also be called the gondola.

Unmanned hot air balloons are popular in Chinese history. Zhuge Liang of the Shu Han kingdom, in the Three Kingdoms era (220–280 AD) used airborne lanterns for military signaling. These lanterns are known as Kongming lanterns (孔明灯).

There is also some speculation, from a demonstration led by British modern hot air balloonist Julian Nott in the late 1970s and again in 2003, that hot air balloons could have been used by people of the Nazca culture of Perusome 1500 to 2000 years ago, as a tool for designing the famous Nazca ground figures and lines.

In 1709 Brazilian cleric Bartolomeu de Gusmão made a balloon filled with heated air rise inside a room in Lisbon. He also built a balloon named Passarola (Big bird) and attempted to lift himself from Saint George Castle in Lisbon, but only managed to harmlessly fall about one kilometer away. This claim is not generally recognized by aviation historians outside the Portuguese speaking community, in particular the FAI.

How Would “Avengers” Look Like If They Were Dinosaurs

Dinosaurs are a diverse group of animals of the clade Dinosauria. They first appeared during the Triassic period, approximately 230 million years ago, and became the dominant terrestrial vertebrates for 135 million years, from the beginning of the Jurassic (about 200 million years ago) until the end of the Cretaceous (65.5 million years ago), when the Cretaceous–Paleogene extinction event led to the extinction of most dinosaur groups at the close of the Mesozoic era.

The fossil record indicates that birds evolved from the ropod dinosaurs during the Jurassic, and consequently they are considered a type of dinosaur in modern classification systems. Some birds survived the extinction event that occurred 65 million years ago, and continue the dinosaur lineage to the present day.

Dinosaurs are a varied group of animals from taxonomic, morphological and ecological standpoints. Birds, at over 9,000 living species, are the most diverse group of vertebrates besides perciform fish. Using fossil evidence, paleontologists have identified over 500 distinct genera and more than 1,000 different species of non-avian dinosaurs. Dinosaurs are represented on every continent by both extant species and fossil remains. Some are herbivorous, others carnivorous.

Most dinosaurs have been bipedal, though many extinct groups included quadrupedal species, and some were able to shift between these body postures. Many species possess elaborate display structures such as horns or crests, and some prehistoric groups developed skeletal modifications such as bony armorand spines.
