[font=Verdana, Arial, Tahoma][size=12px]It said that one of the Lockheed Martin F-16 made a first flight with an empty cockpit last week.[/size][/font]
[font=Verdana, Arial, Tahoma][size=12px]Two US Air Force [url=http://www.enread.com/news/sciandtech/94192.html]pilots[/url] controlled the plane from the ground as it flew from a Florida base to the Gulf of Mexico.[/size][/font]
[font=Verdana, Arial, Tahoma][size=12px]Boeing suggested that the innovation could ultimately be used to help train pilots, providing an adversary they could practise firing on.[/size][/font]
[font=Verdana, Arial, Tahoma][size=12px]The jet - which had previously sat mothballed at an Arizona site for 15 years - flew at an altitude of 40,000ft (12.2km) and a speed of Mach 1.47 (1,119mph/1,800km/h).[/size][/font]
[font=Verdana, Arial, Tahoma][size=12px]It carried out a series of manoeuvres including a barrel roll and a "split S" - a move in which the aircraft turns upside down before making a half loop so that it flies the right-way-up in the opposite direction. This can be used in combat to evade missile lock-ons.[/size][/font]
[font=Verdana, Arial, Tahoma][size=12px][url=http://www.enread.com/news/sciandtech/94192.html]Boeing[/url] said the unmanned F16 was followed by two chase planes to ensure it stayed in sight, and also contained equipment that would have allowed it to self-destruct if necessary.[/size][/font]
[font=Verdana, Arial, Tahoma][size=12px]The firm added that the flight attained 7Gs of acceleration but was capable of carrying out manoeuvres at 9Gs - something that might cause physical problems for a pilot. [/size][/font]
[font=Verdana, Arial, Tahoma][size=12px]"It flew great, everything worked great, [it] made a beautiful landing - probably one of the best landings I've ever seen," said Paul Cejas, the project's chief engineer.[/size][/font]
[font=Verdana, Arial, Tahoma][size=12px]Lt Col Ryan Inman, Commander of the US Air Force's 82nd Aerial Targets Squadron, also had praise for how the test had gone.[/size][/font]
[font=Verdana, Arial, Tahoma][size=12px]"It was a little different to see it without anyone in it, but it was a great [url=http://www.enread.com/news/sciandtech/94192.html]flight[/url] all the way around," he said.[/size][/font]
