Sightings of other objects, including some characterized as drones, flying at altitudes up to 36,000 feet and as fast as Mach 0.75. Another apparent small drone actually hitting the canopy of an F-16 Viper causing damage. These incidents and many more, all occurred in or around various military air combat training ranges in Arizona since January 2020. The events are described in reports from the Federal Aviation Administration (FAA) filed over roughly a three-year period. Overall, the data points to what are often categorized as drones, but many of which are actually unidentified objects, as well as what do appear to be drones, or uncrewed aerial systems (UAS), intruding into these restricted warning areas with alarming regularity."
Mach 0.75 is almost 600 mph. I don't think there's any modern technology that can have a small self propelled drone flying at that speed. For example, this quote: Using two counter-rotating propellers on each engine, the later variants of the Tu-95, like the Tu-95M, are able to hit an incredible top speed of 574 MPH, a world record for propeller-powered aircraft that remains standing today. Admittedly, there is a world record holding speed plane that has done it. So, I guess it would have to depend on the definition of small. A "small" jet powered drone doesn't seem anymore likely to me.
Maybe that's what China WANTS you to think, Bill. Definitely not on Amazon, though... I'll check Ali Baba an' all them sites. You never know what's gonna come up as new on temu-dot-com!
