Nazi Germany's Last Jet Fighter - Argentina 1950
 

Worth a view though I haven't been able to upload a link but if you search for Mark Fenton Productions on youtube,com you should find it.

"When the war ended, lots of Nazi war crimes suspects and scientific personnel fled to Argentina, welcomed by President Juan Peron's regime. One was Kurt Tank, one of Germany's top aircraft designers. With him he carried plans for a last-ditch emergency fighter that had never been built."

This should be it.

Amazing this film survived really. Looks quite a bit like the SAAB Tunan Swedens first jet

Frank Vann was always pleased to note that in the 1980s Kurt Tank and Willy Messerschmitt had offices next to each other at Deutsche Airbus, Munich.

FYI Willy Messerschmitt died at the age of 80 in 1978, having retired from Messerschmitt-Bölkow-Blohm in 1970. Although there was an Airbus Industrie GIE consortium in the late 70's it was nothing close to what exists today. All in all I call BS on that remark.

OK I got the date wrong as I am old enough to think I can rely on my memory of what I was told 30-odd years ago. It was earlier than I thought as I can quote from (p244 of) Frank Vann's biography of Willy Messerschmitt which also shows that they shared an office.
In the autumn of 1969 he was working together with Kurt Tank in an office in the Arabellahaus headquarters of Messerschmitt-Bölkow-Blohm in Munich. Colleagues said what a pleasure it was to see the two great designers, who had for so long been rivals, working together on future projects.

One of the configurations of the Short SB5 was also quite similar.

That's one heck of a stetch to call something made in Argantina in 1959 "Nazi Germany's Last Jet Fighter"
With equal justification you might call a Saturn 5 Nazi Germany's Last Rocket. At least that worked!

And why not - after all, you could argue that SCUDS were a development of the V-2.

Thanks for that...I just got "bad link" when I tried.

Maybe closer to the point the F-86 and Mig 15/17 were also iterations of late german designs
