The data quality is improving. But there are also a lot more drones.

This applies especially to triangular-shaped objects. Reports in the last few years show a lot of those.[1] There are also now large numbers of triangular drones. Here's a really fast jet one from 2017.[2] There are cheaper ones with pusher props. Iran builds a lot of these, in various sizes. So do Ukraine and Russia. You can buy them on Amazon or Alibaba.

There's a group trying to get people to install automated UFO detection cameras.[3] They're pan-tilt-zoom dome surveillance cameras aimed upward, with software to detect objects of interest. They claim 90 sites in the US, but haven't updated that info since 2024. They get good pictures of airplanes, birds, drones, the International Space Station, etc. Not much unexplained. There's another group with the same concept.[4] The standard of detection is that the device should routinely detect and track the ISS when it passes over.

More of those would help. Enough that the same objects are captured from multiple cameras. Then you can triangulate and get range. Also, few optical illusions hold up when seen from three cameras.

Without data, speculation is useless.

China will probably have good sky surveillance soon. There's now a Ministry of Low-Altitude Aviation.[5] Somebody has to do traffic control for all the drones and flying cars in China.
