I just check the chans and am not seeing any activity reported. I’ll keep an eye out. If it were a passenger jet it would have been pretty hard to miss I would think.
And perhaps it was empty - ie, dead heading.... had a he** of a pilot and DIDN’T crash?
Still very odd, if your friend saw things correctly. Surely, though, there could be incident reports required to be filed perhaps, although I have no idea what those might be or how to find them.
OR -
a genuine stealth/disguised flight and good guys (fighter plane) was taking care of biz?
