One thing that was not allowed to happen pre-9/11, however, is the prohibition of electronic item use in flight – and that includes cell phones. It seems that a passenger on a US Southwest Airlines flight did not get the memo, as he simply refused to turn off his handset when asked to – promptly leading to his arrest once the plane landed (safely, of course).
It seemed that there was some fistcuffs going on when the aircraft was about to land at El Paso, Texas, and he refused to comply with the request to turn off the phone. Police handled the situation after the plane landed, while conducting with witnesses on board to verify the story.
