It is no coincidence that many of the UAPs detected where done so in and around our military facilities. Plainly, that is where most of our sensors for detection are. As has been shown, metallic orbs have been captured flying through war zones in the Middle East such as the Mosul Orb of 2016. It should come as no surprise then to hear a study conducted in Ukraine has found UAP traffic over the war-torn country.

Published September 16, 2022 through the Main Astronomical Observatory of NAS of Ukraine, the paper detailed a study of UAP activity in the country. Two stations were set up: the first in Kyiv and the second 120km south in Vinarivka. They used highly calibrated cameras shooting at no less than 50 fps with exposure times of less than one millisecond. Paring this with colorimetry, basically measuring the magnitude (brightness) of UAP, they were able to calculate their estimated size, velocity, and distance.
One key take away is that these UAP are numerous and variable. “Flights of single, group and squadrons of ships were detected.” The biggest variable between them was their size and luminosity. The two main categories were defined as “cosmic” and “phantom.” The cosmic class objects were very luminous and seemed to emit their own light while phantoms were completely black and “absorbs all the radiation falling on it.” Furthermore, the cosmic class was subdivided into size groups named swift, falcon, and eagle. It was also correlated that the faster the object the brighter it shown.
The results are staggering. Here is a summary of targets they detected in the skies above Ukraine.
3m traveling at 14 km/s (31,317mph which 41 times the speed of sound) (p4)
12m traveling at 15km/s (33,554 mph which is 44 times the speed of sound) (p4)
5m traveling at 380 m/s (850mph which is just a bit faster than the speed of sound) (p6)
Another traveling at 282 km/s (630,816 mph which is 828 time the speed of sound) (p6)

As a comparison the fastest manmade object, the Helios Satellites, travel at 157, 078 mph or 70 km/s. The fastest airbreathing jet was the SR71 Blackbird with a record of 2,190 mph or a little more than 1 km/s, and the current F22 Raptor has a top speed of 1,500 mph or 0.67 km/s. Whatever these things are they are faster than any manmade aircraft, if the calculations are correct. So, what are they? I don’t think a piece of airborne debris is going to be flying by at Mach 41. Again however, this paper has not been peer review to my knowledge and if their calculations are off this data means nothing.
