I'm just glad you didn't title this "Peter's World, part Deux."

Probably a Navy guy.

Another interesting airplane incident.

Computers no match for international date line!

I so don't get that. It seems to be too well sourced to be a hoax, but ...

Aviation works in Zulu time, aka GMT. There is utterly no reason I can think of for the airplane to know, or care, where the international date line is. I doubt it is part of the airplane's nav data base, and it isn't as if the IDL follows the 180 degree meridian in any event.

What's more, GPS, which, in conjunction with self contained inertial nav systems, thinks only in Z

The airplane I fly is very highly automated, thinks only in Z, and crosses the IDL without noticing it, because there is nothing to notice.

My hoax detector is quivering.

I saw the same story on enough other sites that I don't think it's a hoax, but I do agree that it probably didn't have anything to do with the IDL. Probably just a computer problem that coincided with that location.

Interestingly, I couldn't find any reference to it on CNN's site. Hmmm.

Much quiet glee amongst the Lockheed Martin guys I work with over this (the F-22 is manufactured by a rival division to theirs.) I will see what I can find out.
