Over the past two weeks I was bombarded by a dozen requests to read a new report by astronomers on Unidentified Aerial Phenomena (UAP) in Ukraine. My response to all of these messages was the same: "I am not sure what to make of the report. Ukraine is in a military conflict with a lot of human-made activity in the sky. This must introduce a lot of noise for any search for objects that are not human-made. In science we aim to maximize the signal-to-noise ratio, and so Ukraine would be the last place on Earth where I would initiate UAP studies."
But last evening I received a special request from a high-level official in the US government to summarize my thoughts on observable signatures of UAP. And so, this morning I checked the UAP report from Ukraine and wrote a paper about it a few hours later.
