WASHINGTON, D.C. — Doug Hughes, the Florida man who flew his gyrocopter into Washington, D.C. and landed it on the west front lawn of the Capitol building last month, was formally indicted by a grand jury on Wednesday.

Facing six charges, Hughes could be sentenced to nearly 10 years in prison.

The grand jury indicted Hughes on two felony charges: operating as an airman without an airman’s certificate, and violating registration requirements involving aircraft.

The remaining charges were misdemeanor counts: three counts of violation of national defense airspace and one of operating a vehicle falsely labeled as a postal carrier.

The two felony charges each carried a maximum penalty of three years in prison and potential fines.

With the misdemeanor charges, he’s looking at a maximum 18 months in prison and potential fines.

Hughes, 61, was scheduled to be arraigned in D.C. federal court on Thursday afternoon.

The resident of Ruskin, Florida claimed he flew his gyrocopter onto to the Capitol lawn on April 15 to bring attention to the issue of campaign finance reform.

His flight started in Gettysburg, Pennsylvania, according to the government’s evidence, taking him through three no-fly zones.

Hughes was employed as a U.S. Postal Carrier, but he did not have authorization to use the U.S. Postal Service emblem on his gyrocopter.
