Earlier quoted context omitted.

When I was at military I attended a few exercises where jets were involved. They don’t go supersonic but pretty close to it so usually once you start hearing something it’s almost over. It’s actually quite terrifying to have a jet coming at you at 800 km/h at low altitude. Very surprising, then very loud and incredibly fast. You also hear passing by jets only once they are long gone. I assume radar is just much bette…

Not just jets, a regular propeller based plane can have that effect: https://www.youtube.com/watch?v=4iOoiEbtf2w

Now I want to hear "Minuet in G for War Tuba" :-) One of the more interesting things about sailing on Lake Mead outside of Las Vegas was that when conditions were right you could hear people talking on the beach more than a mile away. That you could weaponize this phenomena seems pretty obvious in hindsight.

Would this still work for modern military aircraft? I wonder if this + machine learning might still be useful, given radar stealth.

Many of modern aircraft is supersonic so acoustic detection would be useless, even if it technically works.
