WASHINGTON - Lawyers for a Muslim commercial airline pilot say he is being allowed to resume flying after being put on a terrorism watch list. Colgan Air had suspended Erich Sherfern in April. Sherfern, who converted to Islam in 1994, says his job was threatened because his name was on the list. Sherfern's lawyer's released a two-sentence letter in Harrisburg, Pennsylvania, from Colgan Air to the federal Transportation Security Administration confirming that the regional carrier was allowing Scherfen to return to work. It did not mention the watch list or the reason that the company suspended him. Scherfen's wife is a naturalised US citizen of Pakistani origin. The couple sued the federal government last month, claiming their names were placed on the secret list because of their Muslim faith, in violation of their constitutional rights.
