A Pakistan-registered Boeing (BA.N), opens new tab 737 ​cargo plane with five crew members on board lost contact with air traffic control on Tuesday night ‌after reporting a navigational system problem on its way to Karachi, Pakistan aviation authorities said.
Early flight data indicated the 27-year-old converted freighter operated by K2 Airways from Sharjah in the United Arab Emirates possibly crashed into the sea southwest of Karachi after a series of sharp altitude changes before ​a steep final descent, according to flight-tracking service Flightradar24.

Authorities have launched a coordinated search and rescue operation at sea ​through various agencies to locate the missing plane, Pakistan Airports Authority said on Facebook.
