(单词翻译)
We’re going to start in the air. Flight from New York to London usually takes around seven and a half hours. The U.S. Air Force is working on a type of vehicle that could make that trip in less than one hour. Yesterday, they took this thing out on a test flight. We have this animation1 that shows how it was supposed to go. This plane is carrying the X51A Wave Rider. You can see it there underneath2 the wing. The idea was for the Wave Rider to drop off(脱离) the other plane and then show what it’s made for(制造目标). Wave Rider is a hypersonic aircraft. That basically means it’s fast. 4,500 miles per hour fast. It’s six times the speed of sound. The goal for yesterday’s test was for the Wave Rider to go that fast for 300 seconds. It’s not the vehicle’s first test flight. Some of the previous ones didn’t go very well and they had to be shut down(关闭) early.
