Pakistani rescuers search offshore near Karachi for a cargo aircraft that disappears while approaching the southern port. Multiple reports say the plane is a 27-year-old Boeing 737 cargo aircraft and that rough seas complicate the search. According to one account, radar shows the aircraft descending rapidly and its communications are lost before the final descent. Other reporting describes the flight path as involving sharp altitude changes before the plane appears to make a steep final drop into the sea southwest of Karachi. Search teams locate wreckage in the area and begin recovery operations. One source reports that some wreckage is found and recovered, while another specifies that five crew members remain missing after the crash. The incident triggers an active search effort along the coast as investigators work to determine what happened before communications were lost.
