"A bill that would stifle in-flight cellular calls despite emerging technologies that finally make them feasible is headed for the U.S. House of Representatives. The proposed Halting Airplane Noise to Give Us Peace (HANG UP) Act was approved by the House Transportation and Infrastructure Committee on a voice vote Thursday. It would make permanent the long-standing ban on such calls by the Federal Aviation Administration (FAA) and Federal Communications Commission."
Unfortunately, I am not sure how effective this will be. Once internet access is widely available, people can just use their computers or mobile devices with Skype of other VOIP technologies to make calls.
