It is bloody difficult, also for myself!
Even with registration I don’t get results myself!
Pictures taken in France which I found looking for mountain soaring airports.

That also being a tough challenge!

Cockpit reminds me of something homebuilt, maybe a few lines of DNA in it...

Searching for this aircraft has taken me to aeroplanes I'd rather not have known ever existed.............

It's the Colomban MC-30 that I was reminded of but engines and tail arrangement notwithstanding, the cockpit, though similar, is different!

It does look a bit like a Cri-Cri that's taken a beating with the Ugly Stick. ? P-19 Glimmering?

Cri-Cri on steroids perhaps

Can you clarify P-19 Glimmering?
Perhaps a link?
I cannot find any aircraft under that name.

Typing in F-WLDE, I get pictures of Oscar Wilde...

Sorry, a contrived joke. Like a P-38 Lightning, only half the aircraft and rather dim.

I have tried the following sites with no success:

I think I saw somewhere that F-Wxxx is for prototypes, but with numerals following the W.

Not merely a prototype, but pseudonymous? The ultimate spy plane?

This is the hardest challenge of my time on here :ouch: - all sorts of weird aircraft turn up but nothing quite like the challenge - the Cri-Cri is probably closest but still nothing like this horror

I have to ask - did it really fly?

"I think I saw somewhere that F-Wxxx is for prototypes, but with numerals following the W."

Flightless Parrot: F-Wxxx is used for flight testing, after which the registration reverts to a "normal" sequence, but still keeping the last three. So we need to see if there is a regular registration (eg: F-BLDE or others, but that was a Jodel). I've looked but find nothing.

What a challenge!

As it appears to be a homebuilt, I looked for F-PLDE. Naught, not even on DGAC register. Perhaps it was a prop for a film or something.

Thank you all for your suggestions and clarifications.
This might become unsolvable.

Did it Fly?
I guess so

P19 Glimmering is the best suggestion so far!
I was thinking about the Cri-Cri Obesity.

I have send an email to the Sisteron soaring club if they can find it in their visitors logs.

Has anyone explored the search path of the engines?
I think it are no diesels but Hirth 3702.
Hirth

This is the link to Google Maps sisteron, where you can find the photos.

Google maps

The French government site allows searching with a wildcard, so I've done F-%LDE and come up with nothing appropriate (on that site, % is the wildcard character).

Aerodrome Sisteron is the site of two companies into electric flight. Electravia provided the batteries for a Cri-Cri that flew the Channel/Manche. E-props makes propellers optimised for electric powered aircraft; two firms with splendidly transparent names, but a Google search produces no images that look anything like this creature. Anyway, our object seems to have upward pointing exhaust stacks, apparently six per nacelle. Is that plausible?

EDITED: I wrote this before seeing the engine identified: they're intakes, if it is the Hirth, which looks likely.

With no new reactions or suggestions posted for 1 day, I think we have to acknowledge our defeat.
I am in contact with the aeroclub in Sisteron. When they might come forward with additional info I will of course let you know.

Sadly I have to declare OH.

Jeez!! I thought YOU knew Bear...............................

It's defeated us all................... :(

Props looked like Warp-drives. Had one on the Rotax 912 powered Merlin GT.

They don't feather, do they? That thing'd flip on it's back like a Liverpool virgin if an engine stopped!

No, Ground adjustable pitch only.
