I want to welcome each and every balloon enthusiast toPhiladelphia. Thank you for coming here this morning to commemorate the firstballoon voyage in the United States. On January 9, 1793, at ten o'clock in themorning, a silk balloon lifted into the skies above this city, which was, atthe time, the capital of the country.

According to the original records of the flight, the voyage lasted forty-sixminutes, from its departure in Philadelphia to its landing across the DelawareRiver in New Jersey. Though our pilots today will try to approximate theoriginal landing site, they're at the mercy of the winds, so who knows wherethey'll drift off to. Even the balloonist in 1793 experienced some uncertainweather that day. There were clouds, fog, and mist in various directions.
Our reenactment promises to be noting less than spectacular. The yellow balloondirectly behind me is five stories high. It's inflated with helium, unlike theoriginal, which was filled with hydrogen and, unbeknownst to the pilot,potentially explosive. Gas-filled models are pretty uncommon now because of theextremely high cost, so the eighty other balloons in today's launch are hotair, heated by propane burners. These balloons are from all over the country.
