Boeing Condor
The Boeing Condor was a high tech test bed reconnaissance drone aircraft. It had a wingspan of over 200', longer than that of a Boeing B-52. Powered by two 175 hp, six cylinder opposed, twin super-charged liquid cooled Continental TSOL-300-2 engines it had a topspeed of 230mph.
The Condor is totally robotic, with an on board computer to communicate with the computers on the ground via satellite to control all facets of the Condor's missions. The Condors frame is made of mainly carbon fiber composate, as it gives of very low radar and heat signatures.
During its evaluations the Condor logged over 300 hours of mission flying over Moses Lake, Washington. It is now on a display in the Hiller Aviation Museum in San Mateo, California
