U.S. and U.K. spy agencies have been monitoring in-flight mobile phone users for years, according to new revelations. New revelations come from documents leaked by former NSA contractor Edward Snowden. GCHQ intercepted voice and data communications from commercial aircraft using the OnAir service to carry 2G mobile services over the Inmarsat satellite communications network. At the time, GCHQ did not have access to a rival service provider, Aeromobile, French newspaper Le Monde reported Wednesday.”]
