The first human flight was in France in 1783 in a hot air balloon. This means it predated the American constitution when they were officially recognised as a nation with a government.
The first human flight occurred at the same time America formed into a nation.It wasn't a powerd flight like the wright brothers but it was still a flight.
The Americans declared themselves independent in 1776, then around the same time they won the war against the British, two french men flew in a balloon in Paris. This was just before the American constitution in 1787.
