Here's an interview with that nutbar who filed the lawsuit (we were discussing it on that ZOT thread the other day).
Cell phones dont work on airplanes: An experiment was conducted to see if cell phones can work in airplanes. The experiment found that the percent of success rate of contact was:
89% at 2,000 feet,
44% at 4,000 feet,
30% at 6,000 feet,
9% at 8,000 feet,
Flight 93 was flying at 35,000 feet.
A connection would have been impossible.
