First drone story I’ve seen in the New Year.......
The idea the US and China have anti-gravitic technology is laughable.
If we and/or they had it, we would use it in warfare, at the minimum.
The idea of holding such breakthrough tech secret for decades, is laughable.
Consider other breakthrough tech, such as:
Atomic weapons
Jet planes
Digital computers
Encrypted communications
Stealth technology
“Smart weapons”.
All were used to gain advantage in war.
We are seeing the First Drone War in Ukraine.
I don’t see any evidence of anti-gravity drives.
