What Cockpit?

[oncemorealoft]

To keep things going, and as it’s Open House, here is a new challenge. 20 were made and it has an interesting background and a link (obscure) to Ford motors.

[Jhieminga]

Built by Convair?

[oncemorealoft]

Nope! No more clues yet.

[oncemorealoft]

May be a clue is needed? This was a European aircraft from a well known company.

[evansb]

Fokker F-25 Promotor.

[oncemorealoft]

evansb has it. There’s an interesting story behind the aircraft:

https://en.m.wikipedia.org/wiki/Fokker_F.25#/search

“The F.25 was based upon the design of the Difoga 421 aircraft, home-built and -designed secretly during World War II by Frits Diepen, a Ford garage owner from Tilburg, the Netherlands. His intention was to escape from German-occupied Europe to Britain using this aircraft that was powered by a Ford V-8.”

Nice challenge!

Mr Diepen later founded aircraft part supplier
Avio-Diepen.
Now Proponent.
One of the largest independent parts suppliers.
With 9 distribution centers worldwide.

Thank you. I am not allowed to post URLs until I have at least 10 posts. It is OPEN HOUSE.

Nice challenge, I never knew that the F-25 had controls on one side only.

This is the popular story, but it is incorrect unfortunately. It was built using available materials only, but there was nothing secret about it. A model was tested in the NLR windtunnel in Amsterdam and the report about this was published. The company applied for both a registration and a certificate of airworthiness through the normal channels in 1942. Due to 'the current circumstances' this could not be accommodated, and because of this the application as well as the already paid costs were returned. The purpose of designing and building the aircraft was purely commercial.
In Dutch only, but see here for the evidence (includes a lot of photos of the aircraft as well): https://www.hdekker.info/DIVERSEN/Difoga%20421.htm

As we have Still open house:
Does anybody recognize this?

[Jhieminga]

A simulator? 😉

[Self loading bear]

Yes that photo was of a simulator
Here is another one of a simulator of the same type aircraft

Northrop F-20...?

[Self loading bear]

I am sorry but not an F-20.
About a decade later

[Jhieminga]

An Atlas Cheetah C appears to fit the bill. Specifically a SAAF simulator at AFB Makhado

[Self loading bear]

Over to you Jelle
The last is the Cheetah C simulator and
the first photo was of the Cheetah D simulator

[Jhieminga]

It took a bit of searching, but we got there in the end!
Here's another challenge:

Looks like the tandem backseat?
Motorglider?

[Jhieminga]

Not a motorglider.
