I remember a visit to Crete when I was in the Navy in 1963. Crete had a small beach the military used and sometimes airmen would take a car down there and blow the carbon out of it, hence the nickname, "carbon flats."
The Germans placed a lot of mines in Crete during the war and thos things have a long life.
An airman managed to run over one while blowing the carbon out of his car.
It was not pretty.
