With the increasing use of unmanned combat aircraft over the past decade, airplanes without windows have been an increasing presence at air shows around the world. This year’s Dubai Airshow is no exception, and with a few exceptions, most of the offerings come from a local manufacturer. The first example is one of the exceptions. Based on its successful Avanti twin turboprop passenger airplane, Piaggio has developed the Hammerhead UAV. It recently completed its first successful flight.
