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 9, 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 forty-six 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 eighty other balloons in today's launch are hot air, heated by propane burners. These balloons are from all over the country.

　　我想欢迎每一个热气球爱好者来到费城。感谢你们在这个早上来到这里为美国的第一次热气球旅行举行纪念活动。在1793年1月9日的早上，在这个城市还是首都的时候，一个丝绸的热气球在这个城市的上空升起。根据原始的记录，飞行持续了46分钟，从费城出发，横跨特拉华河，在新泽西着陆。尽管今天我们的飞行员会尽可能的接近原来的降落地点，但是他们的气球完全受风的控制，没人知道他们会飘到什么地方。甚至在1793年的气球驾驶者在当时已经熟知并掌握了一些不稳定的天气情况下也是如此。那里有云，雾和使人视线模糊地薄雾从不同的方向飘来。我们承诺这次历史重现的演出必是一次壮观的表演。在我正后方的黄色热气球有5层楼高。这个热气球是由氦气充满，而不是由传统的氢气充满，而且飞行员不知道的是，用氢气充满气球是很有可能爆炸的。充气气球模型因为它的高成本在当今是非常难见到的，所以今天其他80个热气球是由丙烷气炉加热，用热气发射的。这些热气球来自全国各地。
