The opposing lawyer, on the other hand, says the FAA did ask for and receive public feedback (around a thousand responses) and argues that phones are no more dangerous than books flying around the cabin. Unfortunately for the union, it'll have a tough time convincing the court, as the FAA doesn't exactly require airlines to allow the use of mobile gadgets during all phases of flight -- the choice still remains with the companies. Duré says she's confident the court would side with her clients, but adds that the union would be A-OK with a compromise: gadgets can remain switched on during takeoff and landing, but they have to be stowed away until the plane's safely up in the air.
