By Ariba Shahid ISLAMABAD, July 9 (Reuters) - The family of Faisal Jatoi, the Pakistani co-pilot missing with four others after their cargo plane crashed into the Arabian Sea, faced an agonising wait for news on Thursday, as rescuers continued their search. Jatoi was co-piloting a K2 Airways Boeing 737 freighter from Sharjah in the UAE to Karachi on Tuesday night when it went down off Pakistan's southern coast. Pakistani rescuers found the wreckage in a deep-sea search operation on Wednesday.
