Hoping to get some help on a stability analysis of this setup...
Looking for CFD simulation help on this Aero experiment

The discussion centers around a stability analysis of a specific setup, with the original poster expressing skepticism about its reliability. They recount a personal anecdote from childhood, describing how a paper airplane they threw off the Empire State Building managed to hover in front of a window on a nearby building for several minutes. This experience leads them to find the fan video in question not particularly unusual, suggesting that similar phenomena can occur under certain conditions. The focus remains on the analysis of stability and the implications of the anecdote for understanding the setup's behavior.

I'm a bit suspicious about this one.

When I was 10, I threw a paper airplane off the Empire State Building. It flew across the street and leveled out around the 30th floor of a nearby building. The plane hovered in front of a single window for 5 or 10 minutes until someone finally opened the window and shooed it away. So, the fan video doesn't look too unusual to me.
