Douglas Hughes, the Florida mailman who sparked a security emergency when he landed his gyrocopter on Capitol Hill last month, was indicted Wednesday by a federal grand jury.
If convicted on all six counts, he could face nine-and-a-half years in prison.
Huges was indicted on two felony charges: flying without an airman’s certificate, and violating aircraft registration requirements, CNN reports.
He also faces four misdemeanor counts: three counts of violating national defense airspace, and one count of operating a vehicle falsely labeled as a postal carrier.
In addition to the charges, the government wants to keep the letter carrier’s gyrocopter, NBC News reports.
Hughes, 61, previously said he had “no violent inclinations or intent” when he landed the small aircraft on the west front lawn of the Capitol building on April 15. He claims he was delivering letters protesting government corruption.

Hughes defended his flight in a Washington Post op-ed this weekend, writing, “I simply hope by putting my freedom on the line, others might realize how precious their freedom is and join those of us engaged in this fight to preserve and protect our government, of by and for the people.”
