Trump claims there were Airports in 1775 !!??!!

 after making an amazing claim about how the Revolutionary Army took control of
Airports in..........1775 !. This is very unlikely, since the first manned airplanes began to fly ini the 1900s. Here is a quote of part of Trump's speech during the Independence Day military parade on July 4 in Washington D.C.
" Our Army manned the air, rammed the ramparts, it took over airports, it did everything it had to do ". You can see the real speech in the link below:
