I'll take your word for it.  You're right about the windows, it isn't
completely enclosed.  There are typically cell towers AT or very near
airports, which would make it easier to get signal.

GPS is "line of sight" with the unless the GPS antenna can
see a satellite directly, it can't receive it.  Just like in your
have to place the GPS antenna on the front dash facing up/out so it can get
signal, sit in the back seat with it, and you probably won't get signal.

Yes, but that doesn't mean it was a fact.  News has a lot of speculation
intertwined with it...  I'm not saying it was incorrect, but in a time like
that, I really don't believe people pay close attention to the particulars,
like was s/he on a cell phone or the plane's phone...

I'd say the next one of us to go up in a plane, head for the rest room and
see if your phone works there!  I find it interesting that of all the people
on this list, no one has every tried their cell phone on a plane in flight!

Anyway, whether cell phones worked or not on the plane wasn't really the
issue, it was whether they interfered with the avionics, which I still
contend they don't.
