Drone Crash

WASHINGTON — A small drone flying at low altitude crashed in to the White House complex before dawn Monday, the Secret Service said. PresidentBarack Obama was not at home, and the White House said it did not pose a security threat.
The crash prompted an immediate lockdown of the White House grounds until officials could examine the drone. The Secret Service said the 2-foot-long device was a quadcopter – a small, unmanned aircraft that is lifted by four propellers.
