Kindly bear in mind that special photographic equipment for making aerial maps and mosaics, even though available, would be too heavy for this plane to carry with a passenger aboard to operate it, so that this highly specialized type of work is not contemplated.  the taking of oblique photographs with the ordinary cameras that we now have will probably be the extent of the photographic work that will be done.  The very limited carrying capacity of the machine also restricts its useful load to about 30 pounds in excess of one passenger.  This factor will eliminate the possibility of uses involving the transportation of appreciable amounts of equipment or materials. 

For the present the applicability and practicability of using the autogiro in connection with some of our activities is untried and should be regarded as on an experimental basis until further experience has been gained.  We shall appreciate your assistance and cooperation in determining its best uses in our field of work and in the preparation of a worth-while program for its use.
