How is a “rich idiot” smart enough to build a cutting edge drone but dumb enough to accidentally fly it over an Air Force base? It doesn’t make any sense.
If it’s a foreign entity, how do they get it to Arizona in the first place? Why risk starting a war to test out your drone? If China or Russia has this capability, you know damn well the US does too so showing off seems unlikely.
And neither of these theories can identify a motive. Why would a rich idiot be flying near pipelines and air force bases to begin with. Why would a foreign country be doing a dry run so far from home at so much risk?
The only possibilities that I find compelling are domestic terrorist, the US government itself, or something spooky.
