A circa 1957 Hiller quadcopter apparently designed for military roles. The cockpit seems to seat two side-by-side, with a twin-gun emplacement underneath. Other than that, not much can be determined from this piece of art.

Once again Patreon seems to be becoming unstable. So I’ve got an alternate: The APR Monthly Historical Documents Program
For some years I have been operating the “Aerospace Projects Review Patreon” which provides monthly rewards in the form of high resolution scans of vintage aerospace diagrams, art and documents. This has worked pretty well, but it seems that perhaps some people might prefer to sign on more directly. Fortunately, PayPal provides the option not only for one-time purchases but also monthly subscriptions. By subscribing using the drop-down menu below, you will receive the same benefits as APR Patrons, but without going through Patreon itself.
