The final moments of a Pakistan cargo plane that disappeared off the country’s southern coast have emerged as investigators begin piecing together what went wrong aboard the Boeing 737 freighter. Flight-tracking data suggests the aircraft suffered a chaotic sequence of climbs and plunges before crashing into the Arabian Sea, with rescuers later recovering the wreckage and continuing the search for its five crew members, news agency Reuters reported.

The K2 Airways Boeing 737-400 cargo aircraft vanished late Tuesday while flying from Sharjah in the United Arab Emirates to Karachi after reporting a navigational system problem. On Wednesday, Pakistan’s Airports Authority said the wreckage had been found 53 nautical miles (98 km) south of Ormara port following a 12-hour search involving the Pakistan Navy and maritime rescue agencies.

What happened in the final minutes?

According to Pakistan’s Airports Authority, the aircraft reported a navigational system problem at 9:18 pm Pakistan Standard Time while approaching Karachi.

Air traffic controllers attempted to assist the crew, but just three minutes later, radar showed the aircraft descending rapidly before all communication was lost. At the time, the aircraft was about 155 nautical miles (287 km) west of Karachi.

Flight-tracking data from Flightradar24 paints a dramatic picture of the jet’s final moments.

The Boeing 737 reportedly plunged nearly 5,000 feet in less than a minute, then unexpectedly climbed about 6,000 feet within 30 seconds, before entering what tracking data suggests was a catastrophic final dive from an altitude of 36,550 feet.

The aircraft’s last transmitted position placed it at just 1,100 feet above sea level, descending at around 22,400 feet per minute—an exceptionally steep and abnormal rate of descent.

Experts say crew appeared to be fighting the aircraft

John Cox, a former commercial pilot and US aviation safety expert, told Reuters that the available flight data suggested the crew had been struggling to control the aircraft.

“It is possible, in the last portions of it, that the aeroplane was stalled and descending at a very, very high rate,” Cox said.

He cautioned that flight-tracking information alone cannot determine the cause of the crash and that investigators would need cockpit voice and flight data recorder evidence before reaching conclusions.

Search for crew continues

The Pakistan Navy and Pakistan Maritime Security Agency deployed aircraft and ships to search the Arabian Sea before locating the wreckage approximately 53 nautical miles south of Ormara.

Authorities are continuing efforts to recover the five crew members, comprising two pilots, two flight engineers and one support staff member.

Prime Minister Shehbaz Sharif directed authorities to deploy all available resources for the search operation.

Investigation underway

Pakistan is leading the investigation under international aviation rules. Authorities have not yet confirmed whether the aircraft’s cockpit voice recorder and flight data recorder, commonly known as the black boxes, have been recovered.

The US National Transportation Safety Board (NTSB) has appointed an accredited representative to assist the investigation, alongside technical advisers from Boeing, GE Aerospace, and the US Federal Aviation Administration.

About the aircraft

The aircraft involved was a 27-year-old Boeing 737-400 freighter, originally delivered to Russia’s Aeroflot in 1999 before being converted into a cargo aircraft in 2012.

According to Flightradar24, it entered service with K2 Airways in 2024 and was the airline’s only aircraft.

If confirmed, the crash would be Pakistan’s first fatal aviation accident since the 2020 Pakistan International Airlines crash in Karachi, which killed 97 people.
