A Maryland woman has been arrested on charges of sending miniature controls for small unmanned aircraft to China.
The government says the controls are the world's smallest and involve a technology that cannot be shared with China because of national security concerns. The devices can be used to fly small military reconnaissance planes.
Yaming Nina Qi Hanson of Silver Spring, Md., is accused of sending the controls to China in August without a required license. If convicted, she faces a maximum sentence of 20 years in prison and a $1 million fine.
