Recent studies and developments in VTOL aircraft by the U. S. Army have been to fill the requirement for a surveilance or observation aircraft. The low speed helicopter not being satisfactory for the mission, two recent experimental craft incorporate the lift fan principle. Answers to many technical problems have yet been answered, in technical research and operational analysis. Actual operation of Army experimental craft may provide the answers needed.
