I hope this isn’t a fake, I suspect it isn’t. Here’s a paper airplane hovering between two fans. If I had two identical fans handy, I’d totally try this.
Edit: Confirmed fake, see comments.
At 45 feet and 800 lbs this is one of the biggest paper airplanes ever made. It was lifted by helicopter. It traveled at up to 98 mph. Now that is one heck of a science experiment by Pima Air & Space Museum in Arizona.
