UAVs, flying robots and terrorism

A new scare is terrorists with model airplanes. Small, remotely controlled planes could carry up to 50 kilos of explosive and would be undetectable on radars.

But it gets even more advanced than that. Some guy on New Zealand has built his own cruise missile.

If only a scare, then still a testament to the fact that missile-defence and other stuff will be grossly oversized when considering terrorist attacks.
