It has been reported that as soon as a PIA Airbus 310 departed from Peshawar for Abu Dhabi and Dubai on June 21, a giant-size rat was spotted which started running up and down the aisle near the passengers seats. The crisis could have been easily tackled had the PIA staff shown some presence of mind by offering the rat the "hygienic" food offered to the passengers during the flights. DR.
