Raymond Wang, an expert in stopping the international spread of nuclear weapons, from the Middlebury Institute of International Studies at Monterey, California, was one of the first to spot the DF-ZF model.
Writing on Twitter, he noted the programme's narrator didn't specifically refer to hypersonic boost-glide vehicles (HBGVs) or the DF-ZF at any point.
Jamaican sprinter Usain Bolt (born August 21, 1986) is arguably the fastest man in the world, winning three gold medals at the 2008 Olympic Games in Beijing, China, and becoming the first man in Olympic history to win both the 100-meter and 200-meter races in record times.
Bolt also won three Olympic gold medals at the 2012 Summer Olympic Games in London.
Not only was the record set without a favorable wind, but he also visibly slowed down to celebrate before he finished (and his shoelace was untied), an act that aroused much controversy later on.The programme also revealed that Chinese scientists are Built by Chinese Academy of Science with 46 million Yuan (£5 million), the 2.5-metre-wide (8.2 feet), 265-metre-long (869 feet) tunnel is said to be able to blow gusts of wind as fast as 10 times the speed of sound.Mr Jiang said because planes couldn't fly during a lab experiment, they would need a wind tunnel that could generate gusts as fast as the desired speed of the aircraft to simulate a flying environment.In the case of JF12, it could simulate flying conditions between Mach 5 and Mach 9.Mr Jiang claimed that he and his team carry out one experiment every two days, and each experiment last 100 millisecond, which equals to one-tenth of a second.
