Harvard’s Avi Loeb and Dr. Sean Kirkpatrick, director of the Pentagon’s All-domain Anomaly Resolution Office (AARO) co-authored and shared a draft of a scientific paper still undergoing peer review. The paper attempts to use physics to rule out a number of UAP sightings that appear to be “highly maneuverable” objects.
In a nutshell, Loeb and Kirkpatrick find that if some of the UAP really were moving in the seemingly impossible directions and speeds that they appear to be, the friction involved should generate a visible fireball and a corresponding radio signature visible via radar.
