Buried (?) Spitfires.
mmitch,
Interesting link. But whatever the drill brought up, it was unlikely to be wood. Look up "Termite" on Wiki - specifically "Subterranean Termites". I reckon the "crates" might last a month.
But the main stumbling block always remains the "Why". We were the colonial power till Jan 1948. So we have to bury them 40 ft deep to avoid their being stolen in 1946. Who is going to pinch 'em ? When we're chopping them up for scrap all over the place ?
If they turn up, I'll eat my hat (or would, but I think my G.P. might say it was contra-indicated).
Danny.
