I’m well aware of “If it’s grey, stay away” but these three incidents show a complete loss of situational awareness, not basic arrogance. Is it even possible to hack, jam or spoof GPS? Well, yes it is. (Made in China).
Is it possible to confuse the shit out of a Navee ship? Maybe.
Listening to the Porter audio gps/ais failure would explain the OOD’s statement “I have a green light, port aspect on this guy” if their electronics were working I would expect a range, bearing and Cpa.
