“有些东西属于阿拉早就知道的,比如海雕的‘全球鸟’,哈哈,一种是烧油的,涡扇烧航煤,这个续航力42小时,还有一种是烧液氢的,那个飞4天半,关键看鸟出去干吗了,你一想就知道那鸟干吗要飞四天,你就肝颤了,哈哈,”
相当于绕飞地球一圈半。

But the propeller-driven Phantom Eye is no muscle plane. It'll have a pair of 150-horsepower, 2.3-liter, four-cylinder engines. Boeing says the UAV, with a 150-foot wingspan, will be able to cruise at about 150 knots and carry a payload of up to 450 pounds.
It is expected to fly at an altitude of 65,000 feet for up to four days. The initial flight in early 2011, however, is expected to last only about four to eight hours. Between now and then it will undergo a series of ground and taxi tests.
