The US Navy said the two pilots involved in the military plane crash near San Diego are in 'good condition' and under 24-hour medical observation.

As the jet impacted the surface, a massive plume of smoke and water shot into the air before disappearing off the shore near Shelter Island, a neighborhood located across the bay from Naval Air Station North Island.
