Anyone here been successful at making calls from the air? I've tried before and never have much luck at it. Even over populated areas where a lot of towers would be, I couldn't get much of a signal. On my most recent trip I tried text messaging people, but only managed to finally get one to go through as we began our descent. I don't see how those people in the 4th 9/11 plane were able to have conversations with their families. I guess they were a little closer to the ground, though.
I also couldn't get my GPS tracking program to run on the plane. I thought it'd be cool to see a GPS trail going straight across the country and to see exactly how fast we were flying. But it wouldn't work at all. I even had it working on the ground, before we took off and while I was sitting on the plane. But once we got in the air, the GPS signal went away.
