The earliest known world maps date to classical antiquity, the oldest examples of the 6th to 5th centuries BCE still based on the flat Earth paradigm. World maps assuming a spherical Earth first appear in the Hellenistic period. The developments of Greek geography during this time, notably by Eratosthenes and Posidonius culminated in the Roman ...
The aircraft shown here, Chicago, led the first round the world flight in 1924. The first aerial circumnavigation of the world was completed in 1924 by four aviators from an eight-man team of the United States Army Air Service, the precursor of the United States Air Force. The 175-day journey from April to September covered over 26,345 miles ...
They covered 40,529 kilometres (25,184 mi) in a total flight time of 247 hours and 27 minutes. [57] [58] Matt Guthmiller became the youngest pilot to circumnavigate by aircraft, solo in 2014. [59] Since then the record has been surpassed by Australian Lachlan Smart in 2016, [60] American Mason Andrews in 2018 [61] and Englishman Travis Ludlow ...

The tropopause is the atmospheric boundary that demarcates the troposphere from the stratosphere, which are the lowest two of the five layers of the atmosphere of Earth. The tropopause is a thermodynamic gradient-stratification layer that marks the end of the troposphere, and is approximately 17 kilometres (11 mi) above the equatorial regions ...
Mercator's 1569 map was a large planisphere, [3] i.e. a projection of the spherical Earth onto the plane. It was printed in eighteen separate sheets from copper plates engraved by Mercator himself. [4] Each sheet measures 33×40 cm and, with a border of 2 cm, the complete map measures 202×124 cm. All sheets span a longitude of 60 degrees; the ...
The map carved on the globe is an extremely close, if not identical, match to the Hunt–Lenox Globe, a copper globe reliably dated to about 1510. The owner [2] of the Ostrich Egg Globe, Stefaan Missinne, claims that it was made in the early 16th century and is therefore the first globe ever to depict the New World .
Great-circle navigation. Great-circle navigation or orthodromic navigation (related to orthodromic course; from Ancient Greek ορθός (orthós) 'right angle' and δρόμος (drómos) 'path') is the practice of navigating a vessel (a ship or aircraft) along a great circle. Such routes yield the shortest distance between two points on the globe.
