SIMI VALLEY, California: A project manager has demonstrated a tiny spy plane with flapping wings like a hummingbird. Matt Keennon of AeroVironment showed off the high-tech device Friday to journalists at company facilities in Simi Valley. The aircraft with a 6.5-inch wing span can record sights and sounds on a video camera in its belly. Developers say it can perch on a window ledge and gather intelligence unbeknownst to an enemy. The craft can hover and move quickly in almost any direction, a capability defense officials want in a small aircraft for intelligence and reconnaissance.
