Gyrocopter flew in 'under the radar'

The postal carrier charged on Thursday with two US federal crimes for steering his small helicopter-like gyrocopter through protected Washington airspace "literally flew under the radar" to the lawn of the Capitol building that houses Congress, US Homeland Security Secretary Jeh Johnson said as lawmakers raised alarms about security risks.

Johnson said it's too soon to say whether security changes are needed.

Doug Hughes, 61, was charged with violating restricted airspace and operating an unregistered aircraft, crimes that carry penalties of up to four years in prison and fines. He was released from custody and allowed to return to Florida on home detention.
