And our first story concerns a weapon that said to be hypersonic, meaning it would travel at several times the speed of sound.

我们的第个故事是关于个据说是特超音的武器，意味着它的传播度是音的几倍。

We've now built XB-1 which is history's first independently developed supersonic jet, and it's going to be in the air here in the next few months, to prove that all of this technology actually works.

我们现在已经建造出来了XB-1型超音飞机，是历史上第架自主研发的超音喷气式飞机，几个月之后，它会在行试飞，以此来证明所有的些技术都是切实有效的。

Government controlled media in North Korea said the missile was hypersonic, meaning it could fly as fast as 20 times the speed of sound and be nearly impossible to shoot down.

朝鲜政府媒体表示，枚导弹是超音的，意味着它的飞行度可以达到音的20倍，几乎不可能被击落。

And my Supersonics coaches George Karl and Tim Gergich, thank you very much.

还有我在超音效力时的乔治·卡尔教练和蒂姆·格奇教练，非常感谢你们。

Next, we're looking at how NASA is aiming to take commercial travel to supersonic speeds.

接来，让我们了解国国家航空航天局是如何致力于将商业旅行度提升到超音的吧。

Everhart said the time gained by using hypersonic spacecraft could keep the U.S. ahead in " the speed of war" . That is an area where countries such as China and Russia are trying to make gains.

埃弗哈特说，利用高超音飞船获得的时间可以使国在" 战争度上" 保持领先。中国和俄罗斯等国正尝试在领域取得展。

He was on top of the world, an unbelievable 135,000 feet, that's four and a half Mount Everest high, and he became the first person ever to skydive at a supersonic speed.

他站在世界之巅，令人难以置信的13万5千英尺高，相当于珠穆朗玛峰的4.5倍，他成为第个以超音跳伞的人。

Current commercial aircraft fly about 80% of the speed of sound or 85% of the speed of sound, while supersonic airplanes like the Concorde when almost two times as speed of sound.

目前商用飞机的飞行度约为音的 80% 或 85%，而协和式飞机等超音飞机的飞行度几乎是音的两倍。

A change in regulation could lead to a surge of investment in the next generation of commercial supersonic aircraft, making travel faster than the speed of sound, more accessible to everyone.

法规的改变可能会导致对代商用超音飞机的投资激增，以后的飞行度有望都以超音行，人人都得以体验。

She makes some extra cash by calling herself " Dr. Hannah" on commercials and selling wheatgrass and spinach capsules that claim to give you supersonic hearing.

她在广告中称自己为“汉娜医生”，并出售声称能给你超音听力的小麦草和菠菜胶囊，从而赚了些额外的钱。

In two or three years it will be possible, because of the new supersonic jets, to fly from New York to London in two and one-half hours.

再过两三年，由于 新的超音喷气式飞机的发明，从纽约飞到伦敦有可能只用两个半小时。

In addition to flying at extremely high speeds, hypersonic weapons are designed to move in ways that make them difficult to find and destroy in flight.

除了以极高度飞行以外，高超音武器的移动方式在飞行中很难被发现和摧毁。

It was designed to investigate how a large landing vehicle would slow down as it falls through the atmosphere at supersonic speeds.

个降落伞设计的初衷是了解在大气中以超音航行的大型着陆器如何慢慢减。

Everhart said the time gained by using hypersonic spacecraft could keep the U.S. ahead in " the speed of war."

埃弗哈特说，利用高超音飞船获得的时间可以让国在“战争度”方面保持领先。

Spike, another American firm with supersonic ambitions, is developing an 18-seat business jet that doesn't make a loud boom.

另家有超音野心的国公司Spike正在开发种18座的低音爆公务机。

She added that the decision to make hypersonic weapons creates an imbalance that the department must deal with.

她补充说，研制高超音导弹的决定会导致不平衡局面，是国国防部必须要予以处理的。

The supersonic planes being developed today make less noise and are more fuel efficient than the Concorde.

目前正在研发的超音飞机比协和式飞机噪音更小，燃油效率更高。

UBS, a bank, thinks supersonic travel has a future.

瑞银认为超音旅行的前景片大好。

I want to get to the point where a supersonic ticket is actually cheaper than subsonic.

我想让超音的票比亚音的票价便宜点。

The company said the plane is the first supersonic jet to be independently developed.

该公司表示，架飞机是第架自主研发的超音喷气式飞机。
