I want to welcome each and every balloon enthusiast to Philadelphia. Thank you for coming here this morning to commemorate the first balloon voyage in the United States. On January 9th, 1793, at ten o'clock in the morning, a silk balloon lifted into the skies above this city, which was, at the time, the capital of the country. According to the original records of the flight, the voyage lasted 46 minutes, from its departure in Philadelphia to its landing across the Delaware River in New Jersey. Though our pilots today will try to approximate the original landing site, they're at the mercy of the winds, so who knows where they'll drift off to. Even the balloonist in 1793 experienced some uncertain weather that day. There were clouds, fog, and mist in various directions. Our reenactment promises to be nothing less than spectacular. The yellow balloon directly behind me is five stories high. It's inflated with helium, unlike the original, which was filled with hydrogen and, unbeknownst to the pilot, potentially explosive. Gas-filled models are pretty uncommon now because of the extremely high cost, so the 80 other balloons in today's launch are hot air, heated by propane burners. These balloons are from all over the country.
欢迎所有热气球爱好者来到Finodelfia。感谢大家来共同回忆美国的热气球探险。1793年1月9日上午10点，一个 热气球升到了这个城市的上空，这个城市当时是国家的首都。根据飞行的原始记录，飞行持续了40分钟，从Finodelfia起飞到Newgerze的Dellever河中央着陆。尽管我们现在的飞行员想估计当时的着陆地点，但是风是无法控制的，所以谁也不知道究竟是着陆在哪里。即使热气球飞行员在17世纪当时的条件下飞行，在相同的方向上有烟、雾、水汽，我们的模仿也会很不一样。我身后的这个黄热气球有5层楼高，它现在充的是氦气，于原来充的氢气不同，对于飞行员来说非常危险，因为有爆炸的可能。现在用气体填充的气球已经非常少了，因为它的造价非常高。所以今天要看的另外80个热气球是充热空气的，是燃烧燃料来加热的，这些热气球来自全国各处。 ——译文来自: vicky_yurong
