The man who landed his gyrocopter on the grounds of the U.S. Capitol last April was sentenced by a federal judge in Washington to four months in prison.

Douglas Hughes was a mailman when he took flight in the one-man aircraft, armed with 535 letters—one for each member of Congress. He wanted to bring attention to “the influence of big money in politics,” but instead prompted a debate about airspace defense. In November, he pleaded guilty to one felony count of flying without an airman’s certificate. He also lost his job.

He will spend 120 days in prison, followed by a year of supervised release. Hughes is also ordered to stay away from the White House and Capitol grounds.

“Douglas Hughes intentionally violated one of the most secure and restricted airspaces in the world, placing himself and countless others at risk,” U.S. Attorney Phillips said in a release. “His actions led to a lockdown of the U.S. Capitol, major traffic delays, and a diversion of law enforcement resources. Today’s sentence holds him accountable for his reckless acts and hopefully will deter others from attempting to violate the airspace surrounding Washington, D.C.”

But it looks like Hughes has no regrets.

The Floridian was running for Congress, despite complications posed by the terms of his release. He dropped out of the race last week.
