Yeah, since it’s well outside the technical capabilities of existing “jetpack” technologies, it’s almost certainly not what it’s being reported to be.
A stray balloon does seem the most likely explanation, assuming there’s actually something “real” here. I’m reminded of 19th century “UFO” sightings that were entirely based on the expectations created by Jules Verne’s fiction about flying machines - people seeing impossible dirigibles with observation decks and cocktail-sipping passengers.
If it is a balloon, it wouldn’t need to be a particularly big one - it could easily be a party balloon of some sort. Kids let balloons get away from them all the time, and airports are close enough to inhabited areas that a released balloon could easily drift over the airport.
My bet is on a foam cutout of a human being with model aircraft internals. You can make pretty much any shape fly these days with electric motors and ducted propellers.
Believe it or not, I’m walkin’ on air
I never thought I could feel so free
Flyin’ away on a wing and a prayer
Who could it be?
Believe it or not it’s just me
