Interestingly, while it is far less extreme in its ultimate incarnation, the roots of the Short SC. 7 Skyvan go back to the joint effort between Miles Aircraft and Hurel-Dubois to develop an efficient low-speed transport. The Hurel-Dubois/Miles HDM-105 was an Aerovan flown with a high aspect ratio wing as a proof-of-concept. The unbuilt HDM-106 was to have been a larger Lycoming piston-powered production version, and the unbuilt HDM-107 and -108 were to have been even larger turboprop models. In the end, Miles closed its doors and the designs were sold to Short Bros., who kept the same concept but simplified and less extreme. Still, the fairly high 11:1 aspect ratio of the Skyvan wing reveals the HDM influence, and of course the Skyvan went on to spawn the S.330 and S.360. I have always found the Skyvan so ugly it's cute. A homebuilt twin of the same configuration carrying around a little electric car would be great fun.

I agree with 'so ugly, it's cute' I like the idea of a flying RV. A pair of electric scooters should be adequate for transport.

Hehe, we have had a similar thread in the past including examples from Emilien Croses, Dean Wilson, and Marcel Jurca.

But if look at any other planes with similar mission like an-28 - it do not look right.

Skywan look "harmonic" with its all boxy like structure..

Box or no box could be summarised in one way - if you do not need pressurised cab - both coud be good. If pressurised - only round is good.

About drag - i have seen cd table in one old gliders box, and fuselage with round/eliptic surface, hade drag of 0.2, boxy one have 0.27. But yuo use space of box better..
