US devlops flying, bug-like robot spies.

If only we could be a fly on the wall when our enemies are plotting to attack us. Better yet, what if that fly could record voices,transmit video and even fire tiny weapons ?
 That kind of James Bond style fantasy is actually on the drawing board. Us military engineers are trying to design flying robots disguised as insects that could spy on enemies and conduct dangerous misions without risking lives.
The micro Aerial vehicles could be as small as bumblebees and capable of flying undetected into buildings, where they could photograph,record and even attack terrorists.
