Blanchard then crossed the Atlantic and on 9th January 1793 he added to his records by making the first balloon flight in the United States. President George Washington observed Blanchard take to the air at around 10:10am from Philadelphia in Pennsylvania after having given the Frenchman a letter under his seal requiring that no US citizen hinder him. Also watching the launch were the future presidents John Adams, Jefferson, Madison, and Monroe. At 10:56am, Blanchard landed at Deptford in Gloucester County, New Jersey, where he soon attracted a crowd of bemused onlookers who were not only impressed by the manner of his arrival, but also by the President’s letter.
Blanchard’s Journal of my forty-fifth ascension, being the first performed in America, on the ninth of January, 1793 is available in a number of file formats on the Internet Archive site.
