OSHKOSH, Wis. -

The Experimental Aircraft Association says a pilot was killed and his passenger seriously injured when a plane crashed at the Oshkosh airport, where planes taking part in the annual AirVenture convention land.

EAA spokesman Dick Knapinksi says the plane went down on the southeast side of Wittman Regional Airport about 9:30 a.m. Thursday.

Knapinski says the man piloting the custom-built Breezy aircraft died from his injuries. The pilot's female passenger is in serious condition.

Names and hometowns of those involved were not immediately released.

Knapinski says the airport was closed temporarily, but was reopened to departures about an hour later.

The Federal Aviation Administration and National Transportation Safety Board are investigating.
