The Coast Guard says a small Navy plane has crash-landed in Lake Pontchartrain near New Orleans and that one pilot was rescued and the other is missing.

The T-34 plane crash landed Saturday evening. Air traffic controllers at Lake Front Airport notified the Coast Guard at about 6:40 p.m. to say the plane was no longer visible on radar.

Coast Guard crews on two small boats and an MH-65C rescue helicopter were sent to the scene.

The Coast Guard is searching a 1-square-mile area a couple of miles north of Lakefront Airport. The agency says initial reports indicated both pilots were clinging to the aircraft before it sank.

The Coast Guard did not identify the pilots.
