Why does the head of the comet always facing the sun?
its not the head of comet always faces de sun but its the tail that will b formed always away 4m de direction of sun. that's y u`ll c as if head is always towards de sun. n tail is formed by water vapour n dust from comets surface . as de comet moves around de sun a pseudo force called centrifugal force acts on these particles in de direction away from de sun so they flow in that direction n forms de tail which makes de actual comet look like head which is always towards de sun.
Who was the last BOAC comet pilot?
de Havilland Comet jet airliner. . For the 1930s racing aircraft, see de Havilland DH.88.The British de Havilland Comet first flew in 1949 and is noted as the world's first commercial jet airliner to reach production. The Avro Ashton and the Vickers VC.1 Viking non-standard variant fitted with Rolls-Royce Nene turbojets had flown earlier but were experimental models. Early Comet models suffered from catastrophic metal fatigue, causing a string of well-publicised accidents, and the aircraft was withdrawn temporarily and redesigned. The Comet 4 series subsequently enjoyed a long and productive career of over 30 years, although sales never fully recovered. The Hawker Siddeley Nimrod, the military derivative of the Comet airliner, is still in service. In 2007, the original decades-old airframes were being rebuilt with new wings and engines to produce the Nimrod MRA 4, expected to serve with Britain's Royal Air Force until the 2020s, more than 70 years after the Comet's first flight.
When was the first commercial jet - the de Havilland Comet - introduced?
First flight: 29 July 1949. Entered service: 2 May 1952. Go here: http://en.wikipedia.org/wiki/De_Havilland_Comet
Why is the De Havilland Comet so Important?
The De Havilland Comet is important as it was the world's first commercial jet airliner, revolutionizing air travel by significantly reducing flight times and increasing passenger capacity. Introduced in 1952, it set the standard for future jet designs and paved the way for the modern aviation industry. However, its early service was marred by a series of tragic accidents due to structural failures, leading to critical advancements in aircraft safety and engineering practices. The Comet's legacy continues to influence aircraft design and safety protocols today.
Who was the finder of Halleys Comet?
The earliest recorded appearance of Halley's Comet was by Chinese astronomers around 239 / 240 BC. It was recorded by astronomers in many cultures, but was not known to be the same comet. Credit for the discovery of Halley's Comet as the same, returning comet, goes to Edmond Halley. Halley had investigated historical records of 24 comets appearing near Earth between 1337 to 1698, and noted similarities in orbits and other parameters between three of them - the ones that were recorded in 1531, 1607 and 1682. In 1705, he published "A Synopsis of the Astronomy of Comets", demonstrating that the comet which appeared to return about every 76 years was likely to be the same comet. Halley predicted its return in 1758, something which he did not live to see, but which was proven to be the case. We cannot know who originally observed the comet that we now call "Halley's Comet". There were documented observations of the comet as early as 240 BCE. Notes from the Talmud indicate that this was a re-appearance of the comet, so people had remembered seeing it before. Halley's Comet is a fairly short-period comet, becoming visible about every 76 years. It got the name "Halley's Comet" because in 1705, Edmund Halley predicted the year that it would re-appear in 1758. He based this on historical observations. The French astronomer Nicolas Louis de Lacaille proposed naming the comet in Halley's honor in 1759.
