Amiot 357

Today it's the turn for a French secret project of the World War 2 as this aircraft wasn't discovered until France fell.
The Amiot 357 was a prototype of a high altitude bomber featuring a pressurized cockpit based on the Amiot 350 twin-engined bomber family.
It was powered by two Hispano-Suiza 12Z-89 engines turbocharged delivering each of them 1200hp of power in order to achieve good performance when on high altitude.
It was being constructed at Amiot's factory in Le Bourget, close to Paris during the first quarter of 1940 and the prototype was almost finished when the German troops captured the factory on 14th June 1940.
As this bomber would've been a true breakthrough in French bomber technology, we imagined how a possible French high-altitude camouflage would've looked like and therefore applied an hypothetical version considering that France would've resisted the Blitzkrieg.
