Here's a disruptive British-made change, in all probability bought by the Pentagon, being demonstrated in 2007:
And here's atypical, more exactly higher homebrew-looking establishment, flying in France certain the dreadfully time:
Apiece the first-class craft utilise the Coanda renounce, naked by Romanian instigator Henri Coanda in the late 1920s and earlier 1930s, which exploits the way that air flows over a rounded cessation to establish lift.

I've recurrently wondered whether undeniable of these population may have seen tests of unpolluted experiential and - as one commenter has noted below -unstable aircraft.
The design of what's more these mini-saucers in addition reflects sculpt era 1950s and '60s UFO sighting reports, but this is supposedly exhibit to enlarge the Coanda renounce, rather than their retro-saucer stylings.
As I show in "Illusion Men", there's nonexistence alien, or match notoriously dissimilar, about disc-shaped or round-winged aircraft, which have been gloriously flown in the function of the earlier 1930s, and now and then stem goodwill dressed in archetype [in fact a pond lb10 decision get you your very own RC saucer for domicile use].
As a case in charge, here's bleeding footage of two of the imaginative hand American designs, the Arup S-2 and S-4. Certain and built by CL Snyder and Raoul Hoffman, these flying heels performed awfully well in the air but were never able to get off the ground commercially, on the other hand the design would re-emerge in the 1940s as the US Navy's renowned XF5u flying Flapjack':
