Two pilots and two flight officers whose jets crashed off the coast of North Carolina this morning were recovered and are receiving medical attention, according to a Thursday release from Naval Air Force Atlantic.

The two F/A-18F Super Hornets, who "were involved in an in-flight mishap" around 10:40 a.m. were flying a routine training mission off Cape Hatteras, the release said.

"We don't know exactly what happened yet," AIRLANT spokesman Mike Maus told Navy Times, but an investigation has been convened.

Coast Guard Fifth District received a call that two jets had collided around 10:30 a.m., according to a Coast Guard release.
