The Makhonine MAK10 was a curious, yet brilliant aircraft. It featured a sliding wing that increased the size of the aerofoil for take off and landing, and decreased it for high speed flight. Although its size and the low power of its engine made performance less than impressive, it still demonstrated the potential of variable geometry wings more than 20 years before the idea became mainstream.

As far as I know, there are no books on the Mak10. This video is therefore a collection of information found on the internet. Interesting sources:
