Ran across this in the interwebs. The person filming is watching a UAV type of vehicle kind of close to F-35 flight testing when the F-35 breaks the sound barrier in a big way, followed by its F-16 chase (which was much more quiet)!!

Just FYI for clarity's sake (sorry if you know this already), that's not the F-35 "breaking the sound barrier" as such. Meaning, that's not right when it goes supersonic. You get a sonic boom the entire time the aircraft is supersonic. You'll only hear it when the boom passes over you.

"Two and a Half Men" was filmed in front of a live ostrich.

so much for stealth... BOOM we're coming. Count the booms and you'll know how many .. Using a weather radar that tracks lightening strikes should show the plane's path.

Certainly audible detection of aircraft is possible, and it has been done. It's limited because of its fairly short range, and largely trails the aircraft (completely so in the case of supersonic flight). Presumably if it's a problem for a particular ingress route to a target, you'd expect a subsonic approach.

Lightning detection is about detecting the electrical impulse of the lightning, not the consequent thunder, so would be useless for detecting sonic booms.

I may be wrong, but I thought he was joking.

F-35 Lightning, you know......

I was. Sometimes discussing the F-35 needs a little humor without a big sign (HUMOR AHEAD)

He got me too. The only thing that would give it away was if instead of "BOOM we're coming" he would have written "BOOM we've were here". As 'lightening strike" would refer to the location where the F-35 "struck".
