You bet! See Man detained outside White House for trying to fly drone for an example on what not to do with your UAV...

Federico was right on in his comment in that this is a weak 'answer' and yes, I know better than that.

While not answering the body, this question does answer the one in the title.

See Man detained outside White House for trying to fly drone, as well as related stories of that day, for an example on what not to do with your UAV...

As a synopsis, if I remember the details correctly, a US Federal employee was at a friends house in Washington D.C. and they were playing with the friend's new quad-copter (some might call it a drone). There was much drinking and celebration and the man was flying the quad while quite drunk. He flew it towards the White House and it disappeared. It landed itself on the White House lawn. So, yes, a 'drone' can fly beyond radio range.
