Actually, no UAP's have ever been recorded or at least would not have been. But in 2050 at a Catalina demonstration of a time traveling hovering camera (used primarily on new Teslas to go back in time to record traffic accidents to determine fault), Elon Musk sends them back in time by tossing the devices in the air, assuring the audience that they would be undetectable even by fighter jets of the time. Unfortunately after 2 throws of the devices back in time, the audience chuckles looking at the big screen behind Elon as both are detected and recorded by F-18's thereby changing the time continuum leaving us to wonder what they were for over 30 years. "Guess we have some improvements to make before production" Musk replied.
