The Coast Guard says an overnight search yielded no sign of a Navy plane and two pilots who failed to return from a flight.

Petty Officer Randy Hale early Thursday told The Associated Press that search aircraft were out all night and "we haven't been able to find anything as of yet."

The search began Wednesday afternoon for the crew of a Navy T-34 training aircraft when a controller at Naval Air Station Corpus Christi lost contact with the pair.

The single-engine trainer's last known location was near San Jose Island, east of Rockport and 2 miles off shore in the Gulf of Mexico.
