Narrator: A tiny airplane, the AV Pointer serves for surveillance -- in effect, a pair of roving eyeglasses. A cutting-edge example of where miniaturization can lead if the operator is remote from the vehicle. It is convenient to carry, assemble and launch by hand. Battery-powered, it is silent and rarely noticed.
