"I think the X-59 could be significant," says Christopher Combs, University of Texas at San Antonio. Despite the advances in computer modelling and wind tunnel technology, it is still too much of a risk to build a quiet supersonic passenger aircraft without real-world evidence that the technology will work. That might be about to change if years of research into how to create a quiet sonic boom come to fruition Nasa and the secretive "Skunk Works" of aircraft manufacturer Lockheed are trying to build an aircraft that creates it. With that ban – and others like it – went the business case for aircraft like Concorde. In 1973, the US government banned commercial supersonic flights over land in the United States. Only this time, if all goes to plan, nobody on the ground will notice. Now, in 2023, the latest X-plane – the X-59 Quiet SuperSonic Technology (QueSST) aircraft – is aiming to repeat a feat achieved by the first X-plane – break the sound barrier again. The fastest of the X-planes would take their human pilots to more than six times the speed of sound. Flights by cutting-edge aircraft like the X-1 and X-15 paved the way for the eventual triumphs of the Apollo programme and Neil Armstrong's first steps on the moon.
The legend of America's X-planes was born in the mid-1940s and flourished till the 1960s, when rocket planes flew to the edge of space. It was the ninth powered flight of the experimental Bell X-1 aircraft, and onboard the pilot wrestled the controls as the aircraft's stability fluctuated as it's speed increased. The game has 4 languages: English, Russian, French and German.In 1947, the first clue onlookers at Muroc Army Airfield, California, had that the sound barrier had been broken was a thunder-like sound, or bomb burst.The game include single game with story mode and local multiplayer.You have cameras, a map, a flashlight and binoculars. You need to find the creature, because in the past you were a hunter and have a rich experience in working with wild animals. They think that this is unknown to science a new kind of beast, but you are sceptic and you think that it's just an animal. Your name is David Smith and you came to Grackham National Park at the request of a group of archaeologists led by Dana Foster. You are a scientist from Central University. The Central University sent you on a business trip to inspect the place of the excavations and study the remains. Nearby, a group of archaeologists finds a cave and skull of an unknown creature. Local hunters find strange footprints, torn animal bodies. Their car with traces of blood was found in the forest.Īt night a roar is heard from the forest.
Two teenagers were disappeared in the vicinity of the Grackham National Park.
