Military aircraft intercepted two small civilian planes Friday in the vicinity of Camp David, Maryland, where the Group of Eight is holding a summit, the North American Aerospace Defense Command said Saturday.

The crafts, both Cessna 172 general aviation planes, were out of radio communication, NORAD said.

An F-15 Eagle intercepted one craft around 7:03 p.m. ET. It landed at the York Airport in Pennsylvania after it left the temporary flight restricted area. An F-15 and an HH 60 Black Hawk intercepted the other plane around 7:17 p.m. ET. It eventually landed on a grass runway in Pennsylvania.

Law enforcement personnel were interviewing both pilots, NORAD said.

NORAD is a Canadian and American command dedicated to preventing air attacks against North America.
