Check it out:

Police arrested a man who steered his tiny, one-person helicopter onto the West Lawn of the U.S. Capitol Wednesday, surprising spring tourists and prompting a temporary lockdown of the Capitol Visitor Center.

Capitol Police didn’t immediately identify the pilot or comment on his motive, but a Florida postal carrier named Doug Hughes took responsibility for the stunt on a website where he said he was delivering letters to all 535 members of Congress in order to draw attention to campaign finance corruption.
