A single-engine plane strayed into restricted airspace near the U.S. Capitol in Washington Friday, sparking a brief security scare.

Authorities moved to evacuate the north lawn of the White House and parts of the U.S. Capitol before the all-clear signal was given a few minutes later.  The Senate was in session, and briefly went into recess.

Officials said the pilot of the plane complied with authorities, and landed at a local airport.

There have been several similar incidents since U.S. officials tightened restrictions on airspace in Washington after the September 11, 2001, terror attacks.
