d. ARUP Tailless Monoplane

Jane's "All the World's Aircraft" (1935 edition) describes this airplane as "a two-seat machine with a 70 h.p. LeBlond engine.... This has a high aspect ratio wing with straight leading-edge and built in nacelle...." In plan form, the wing is almost semi-circular.

An Air Force film, "Aeronautical Oddities", shows this airplane in flight at South Bend, Indiana and in some attitudes appears identical to the photograph included in Appendix "C" as Figure 4. Although it is believed that the ARUP Manufacturing Co. is no longer in existence, it is possible that later models of this or similar U.S. civil aircraft may have been observed.
