A full-scale emergency search and rescue protocol is active in the Arabian Sea after a Boeing 737-400 freighter operated by Karachi-based private freight carrier K2 Airways vanished from secondary radar systems late Tuesday night. The aircraft, registration AP-BOI, was tracking a commercial cargo route from Sharjah International Airport (SHJ) to Karachi's Jinnah International Airport (KHI) with five crew members on board when all radio and transponder communication abruptly cut off.

According to technical logs released by the Pakistan Airports Authority (PAA), the flight crew contacted the Karachi Area Control Centre (ACC) at 21:18 PST to alert air traffic controllers of a progressive navigational system malfunction. While ground control immediately initiated emergency directional guidance vectors, the flight data took an alarming turn three minutes later.

The Final Telemetry and Flight Path

Automatic Dependent Surveillance-Broadcast (ADS-B) tracking archives managed by flight tracking network Flightradar24 outlined a highly erratic vertical speed envelope. Before the catastrophic loss of telemetry, the converted freighter registered an unexpected altitude drop, a brief corrective climb attempt, and a second sudden plunge.

The last broadcasted data block captured the aircraft at roughly 1,100 feet over the ocean, exhibiting an extreme vertical descent rate of approximately 22,400 feet per minute. PAA officials confirmed that the final radar handshake occurred roughly 155 nautical miles west of Karachi, positioning the primary search zone near Ormara along the Balochistan coastline.

In their final radio transmission back to Karachi ACC, the flight crew stated they were "rolling or floating"—a phrase currently being scrutinized by the Bureau of Air Safety Investigation. Furthermore, data indicates the airframe encountered Global Navigation Satellite System (GNSS) signal interference shortly after leaving the UAE, although investigators emphasize it is too early to establish causation.

Aviation Assets Mobilized for Search

Aviation experts note that the telemetry signature points away from routine mechanical structural failure. Aviation analyst Imran Aslam stated to local broadcasters that even under complete dual-engine flameout conditions, a Boeing 737 airframe retains a standard aerodynamic glide ratio and does not experience such a vertical dive profile without catastrophic aerodynamic or structural upset.

The PAA has fully stood up its primary Rescue Coordination Centre (RCC) to orchestrate a multi-agency response, though seasonal monsoon currents and rough sea swelling are complicating maritime tracking. The Pakistan Navy has deployed its surface warfare frigate PNS Zulfiqar directly to the coordinates of the last known position. Aerial tracking grids are being swept by a Pakistan Air Force SAAB surveillance aircraft alongside a Pakistan Navy ATR maritime patrol platform scrambled from Turbat, while the Pakistan National Shipping Corporation has diverted its commercial merchant vessel MV Lahore to assist in locating the five missing aviators.
