K2 Airways 737 Plunged From Cruise Altitude After Navigation Fault; Cause Hinges on Flight Recorder Recovery

A K2 Airways cargo Boeing 737 reported a navigational system fault on approach to Karachi on July 7, then descended rapidly from 36,550 feet into the Arabian Sea, killing five crew members. Flightradar24 data shows erratic climbing and dropping before an uncontrolled final dive—suggesting catastrophic in-flight failure rather than pilot response. Locating the submerged fuselage and flight recorders will determine whether navigational malfunction, autopilot disconnect, or structural failure caused the crash.
