“...and were reportedly buried for possible future use.”
Maybe they did something more than just bulldoze a trench. But 70 years, I dunno...
There was a story a few years back about Spitfires that had been buried (in shipping crates, partially disassembled) in Malaysia. Never heard any more about the fate of those.
If the FWs were still in crates or packed away in someway…maybe?
