SYDNEY: Australian and US scientists have successfully tested hypersonic aircraft technology, which could revolutionise international flight, officials said Friday.The trial was the first of up to 10 tests to be conducted at the Woomera desert range as part of a joint US-Australian military research operation, said Defence Science Minister Warren Snowdon. The programme, called Hypersonic International Flight Research Experimentation (HIFiRE), is investigating hypersonics technology and its potential for next generation aeronautics. "Hypersonics is the study of flight exceeding approximately five times the speed of sound, and this trial has successfully tested the flight and mission control systems that will be used in future experiments," Snowdon said.The test vehicle was carried into space aboard a rocket launched from Woomera and then dived back into the atmosphere to test the hypersonic flight technology. Nitrogen gas valves were used as thrusters to manoeuvre the craft in space and correctly position it for reentry into the atmosphere, offering scientists a "wealth of new data," Snowdon said. Hypersonic technology offered "quantum leaps" in speed and fuel efficiency and had the potential to dramatically reduce intercontinental travel times, said Snowdon.
Sunday, February 28, 2010 HAVANA: Hundreds of wealthy merchants and cigar aficionados from all parts of the world gathered in Havana this week to bid high stakes for humidors full of premium cigars. Cuba's annual Habanos festival ended on Friday night with an auction of ornate humidors of cedar and mahogany stacked with hand-rolled stogies that raised 800,000 euros ($1.09 million dollars). Habanos S.A. executives this month said cigar sales fell 8 percent to $360 million in 2009, so they have created the Julieta, a smaller, milder version of the Romeo y Julieta cigar, aimed specifically at female smokers. Women now make up only 5 to 10 percent of customers for Habanos. But even with the creation of the Julieta, Garcia said Habanos has only modest hopes for 2010 sales, due largely to a weak economy in Spain, the biggest market for Cuban cigars. The flavor of premium tobacco relies on the soil and climate in which it is grown. The western province of Pinar Del Rio, famous fo...
