 FACT: The TNT&G team saw a need to prove, if they could, that the  pilot had been issued the warning about the bad weather by an Air  Traffic Controller. In reality, the pilot, and not the Air Traffic  Controller, is responsible for obtaining the weather, using all  means available. Weather changes, and if a pilot is not in contact  with Air Traffic Control, he would not necessarily know about them,  but the responsibility rests with the pilot, not ATC.
