A sudden Boeing 737 jet operated by K2 Airways vanished shortly after leaving Sharjah Airport on July 7 2026. Contact was broken just after departure while the plane was loaded with mail and goods on board. Search crews now scan along the coast near Karachi. Early radio checks indicated the pilots fighting to control the aircraft. Investigators say no signals arrived before it dropped out of view. Officials warn finding the rubble will require time but it's the only way to understand what broke down.
