11 airspace violations around Camp David

CAMP DAVID (CBS) -- The Secret Service reports that there were eleven violations of temporary flight restrictions around Camp David, the presidential retreat in Maryland, on Sunday.

President Bush was visiting Camp David this weekend, but the Secret Service said that all of the incidents occurred while Mr. Bush was attending a memorial for fallen firefighters in Emmitsburg, Maryland.

The Secret Service reports all of the incidents were believed to be inadvertent, noting that flight restrictions are routinely changed whenever the president travels to or from Camp David.

WTOP Radio is reporting that at least one plane was escorted by F-16 fighter jets to the ground at the Westminster Airport in nearby Carroll County.
