A 61-year-old man landed a small gyrocopter on the lawn of the U.S. Capitol Wednesday to protest the permissive campaign finance system enabled by the Supreme Court’s Citizens United decision.

The pilot, Doug Hughes, is a mailman from Florida. He was immediately arrested upon landing the aircraft.

The Tampa Bay Times has published an in-depth profile of Hughes. He was first driven to political action two and a half years ago when his 24-year-old son committed suicide by crashing his car into another man, killing both men.

His plan involved flying the copter at a low altitude and a mere 45 miles per hour — too close to the ground and too slow to be overtaken by any airplane — while wagering that government officials wouldn’t actually shoot down a 61-year-old who had publicly declared his non-violent intentions.

“I’m not promoting myself,” Hughes previously told the paper. “I’m trying to direct millions of people to information, to a menu of organizations that are working together to fix Congress.”
