6. Wright is one of the most original figures of British Romantic painting, and this composition, held in the same private collection in Derbyshire since 1840, had an approachable low estimate of 100,000 because of condition issues and — not insignificantly — the fact that it was a charity donation to benefit Syrian refugees. As a result, at least three bidders pushed the price to 665,000 with fees.
西西软件园 In 2010, the Martin Aircraft Company introduced a jetpack it called "the world's first piratical jetpack." The jetpack even won a spot in Time's Top 50 Inventions of 2010. While its development has been on since 1981, the world's first jetpack is known to have flown in 1958. It was designed by Wendell Moore, a researcher at Bells Aerosystems. Early prototypes of Wendell's jetpack could reach a height of 5 meters (16 ft) and remain airborne for three minutes. This attracted the attention of the US Army, which funded the project with $150,000. Several test flights were later done for the US Army and even for JFK himself. The army later stopped paying for more research into the project because the flight time and distance were not convincing enough. NASA also wanted to use the jetpack for their Apollo 11 mission to serve as backups in case their lunar module malfunctioned. They later changed their minds, going for the lunar rover instead. After this setback, Bell discontinued further research on the jetpack.
