I'm not seeing it either. I can't speak for comms or other systems, but for navigation, every GPS system I've seen gets its date/time stamps from the satellites, in GMT. The Date Line doesn't mean squat when you're using GMT.
That was my thinking as well, but I guess these guys were using a geosynchronous sat system that was not GPS, or I suppose thats the inference, and the time signal was somehow linked to the position matrix in the nav system , so that it couldn't do a proper return affirmation signal on the time line? This caused all computers to crash and they were on VFR?
Sounds like a bas akwards nav system that won't work unless all the clocks are synchcronized to local way point time zone progression?
I have a hard time believing that , but I suppose its possible.
After all we must bomb the enemy at exactly the planned local time, not Zulu?
And all the computer systems crashed? Sounds too urban legendary for me. But what do I know, with all the new systems coming on line these days.
Or maybe F22s are also able to engage in time travel?
Just kidding.....
