Airlines in the US could soon allow their passengers to make phone calls and use data connections while in the air, and today is the final day for opinionated fliers to let regulators know whether or not they think thats a good idea. The change all comes down to the approval of a recent FCC proposal, which would allow airlines to begin installing equipment onboard planes to make phone use possible. The FCC will only approve the technical ability to allow phone calls Presumably, reports of potential technical issues might be more valuable than complaints about not wanting to listen to noisy passengers, but the latter is about all the FCC has gotten.
