And the real tragedy was how much of this intriguing materiel was destroyed by neglect and a savage winter just after the war. All those aircraft, left out in the open for "future evaluation" (including some interesting "experimental' jobs), suffered water ingress from all that lovely English "liquid sunshine".
So, winter rolls around with a vengeance, the water freezes and "pops" riveted joints all over the place.
Enter the bulldozers and fire-axes (and the scrap merchants), to make the place look "tidy".
How many "surplus"
British aircraft conveniently suffered the same fate post-war? Probably, nobody cared; they just wanted their saucepans back. And thereby, hangs another tale.
With the onset of war and rationing, nutrition became a serious problem. As was later discovered in India, aluminium cookware is NOT a good thing for folk with a low-iron diet. You get iron from red meat, or VAST amounts of certain green, leafy vegetables. The alternate source is the microscopic amounts scraped from iron vessels during preparation and cooking.
A notional return to old-fashioned iron pots during the rationing times may have provided just enough dietary iron to keep things working.
In the absence of sufficient iron, aluminium is toxic to the human system and causes serious nervous issues, by accumulating in the brain and playing merry hell with its function. A famous example is Buddy Ebsen, of "Beverly Hillbillies" fame who was the original actor to play the "Tin Man" in "Wizard of Oz". All that Aluminium-powder "make-up" got to him very badly and the rest is history.
