jetliner's shielded electronic systems. Safety researchers Tekla S. Perry and Linda Geppert point out that shielding and other protections degrade with increasing age, cycles of use, and even some maintenance procedures, as is also true of the shielding in PEDs, including mobile phones. Several reports argue both sides of the issue in the same article; on the one hand they highlight the lack of definite evidence of mobile phones causing significant interference, while on the other hand they point out that caution in maintaining restrictions on using mobile phones and other PEDs in flight is the safer course to take. The debate on other issues Social resistance to mobile phone use on flights Many people may prefer a ban on mobile phone use in flight as it prevents undue amounts of noise from mobile phone chatter. AT&T has suggested that in-flight mobile phone restrictions should remain in place in the interests of reducing the nuisance to other passengers caused by someone talking on a mobile phone near them. Competition for airlines' in-flight phone service Skeptics of the ban have suggested that the airlines support the ban because they do not want passengers to have an alternative to the in-flight phone service such as GTE's Airfone. Andy Plews, a spokesman for UAL's United Airlines, was quoted as saying "We don't believe it's a good safety issue...We'd like people to use the air phones." Current status In flight technology On 31 October 2013, the FAA issued a press release entitled "FAA to Allow Airlines to Expand Use of Personal Electronics" in which it announced that "airlines can safely expand passenger use of Portable Electronic Devices (PEDs) during all phases of flight." This new policy does not include cell phone use in flight, because, as the press release states, "The FAA did not consider changing the regulations regarding the use of cell phones for voice communications during flight because the issue is under the jurisdiction of the Federal Communications Commission (FCC)." This FAA press release was quickly followed up by an FCC press release entitled "Chairman Wheeler Statement on In-Flight Mobile Services Proposal" in which FCC Chairman Tom Wheeler states, "modern technologies can deliver mobile services in the air safely and reliably, and the time is right to review our outdated and restrictive rules." This has led to media speculation that the use of cell phones for voice communication on board an aircraft
