Off topic, but that incident Dolby proves that nothing is so dumb to not be possible. How that ever got on the air, considering how many people had to have seen those made up names prior to the anchor speaking them and the picture going up.....
It's only been a couple of days, and the area of water being searched is larger than the state of PA, it just may be a matter of they haven't found the debris area yet.
I find it very strange that one family was able to connect to a family members phone who was on board - could it really be floating and working from some cell tower someplace, or have fallen to dry ground someplace and survived? I don't know if this story has been discredited or not yet, but it made me think of that gopro camera video on youtube of the camera that fell into a pig farm, and was found working 6 months later with the video intact - based on that it's possible for a cell phone to survive a fall from high altitude I suppose.
