talking of rubbish dumps.....
As a kid in Clacton-on-Sea, I made frequent sorties to a lump of land with a gully running through, known locally as"Smith's Pit" It was probably just fly-tipping, but us kids found all sorts of treasures therein.
protruding from the side of the gulley was part of a rusty cylindrical tapered shape. Local legend had it that this was the hull of a captured German submarine!
It was late 50's and Alton Park primary school was being built at the end of the road,so large numbers of kids walked past "smitty's" every weekday.
Some years later ,off "the Point" Canvey Island (Thames Estuary) a group of us explored parts of a wrecked aircraft on/in the mudflats at low tide. I still have the chunk of cylinder-head with a bent,but shiny valve in it, that Irecovered that day,late 60's.
Again, local legend had it that it was a shot-down German bomber,
IIrc, there were fairly intact flap and a landing-gear leg on the surface and a lot of other stuff poking out of the silt.
