Was this connected to the work carried out on the SNCASE SE=3110? however most images of that aircraft showed two bladed rotors. However I think this one is the Borgward Kolibri

Found the original video from which the challenge image came from. Brilliant challenge Graham great fun searching.. Open House if I am correct in saying the aircraft was the Borgward Kolibrri

Yes, you are correct Mel - Open House it is then. :ok:

try this - won't last long I think

Perhaps the Manuel Crested Wren or the Kestrel?

No - there was only one built I believe and it's in a museum

I think this was the designer​​​​​​​

A glider?

Yes - and a notable first.

A water-glider?
But 'first' in what way?
By no means the first water glider. That was done in 1905
First with flaps perhaps?
Italian by any chance?

It is very definitely a first - and it isn't Italian

It is a while after 1905 tho'.................

DFS See Adler German glider designed by Hans Jacobs and flown by Hanna Reitsch?

I looked at the Seeadler earlier and did see that it’s ailerons had wwwww braces and not xxxxx.
So I would be surprised if Seeadler would be correct.

Not Seeadler. Mid fin mounted tailplane and fin shape completely different..
One or two Polish gliders from the '30s have a similar fin shape but none were waterbirds.

Its not Portuguese is it? Otherwise no idea. I'm stuck.

Possibly 'The Welsh Harp':confused: But the floats look different...Slingsby Water Falcon:confused:

Not German - meleagertoo is correct - it is Portuguese :ok:

It's called the Varela Cid and resides in the Muesu do Ar at Sintra which explains why I didn't recognise it as I missed going there last time in Portugal, and despite searching their exhibits list on first seeing what appeared to be a Portuguese flag on the wall in the challenge photo a couple of days ago didn't find it listed - or just didn't spot it. The flag was the giveaway.

Translated "Built by Artur Varela Cid, at the time a student at Técnico, the “Portugal” rose to an altitude of 140 meters on its maiden flight in 1934. became the third hydro glider to fly in the world, at a time when the knowledge of aeronautics was developing at a great pace. It flew a second and last time in Póvoa de Santa Iria and from there it went into rest, but also for the history of engineering and Portuguese aeronautics. It made an invaluable contribution to the knowledge of the aerodynamic components of flight and also presented itself as a good instructional tool for aviators. It has been exhibited at the Museu do Ar, in Alverca, since 2016, surrounded by motorized planes."

However finding out anything about Artur Varela Cid himself is difficult, there isn't much on the internet and most of that is in Portuguese.


Vast detail on the contemporary science of gliding and some pics of the Varela Cid , Page 507 onwards (in Portuguese);

Great challenge, that one!

A picture to hold the fort until 13:40

What would the reason be to land a glider in the water, i.l.o land? Do you have to haul the plane onto land to get it in the air again? Or could you start it from the water? Most puzzling.
