I would not try that if i where you ... dont you remember the Kola deep hole experiment ? Hell is waiting there for you !!!!
.. Ahh, just kidding.
Reality is, they stopped funding it after the fall of CCCP (so they messed up the year too) but ended the research near 2000 at about 13 km depth - a great number of interesting stuff were found out of there :
Around 11 km a great abundance of precious metals was found, and much much water - (from aqueous anorganic cristalline substances, witch at those temperatures and pressure loose wather out of the crystaline mesh, but cant escape the crust because of the waterproof layer at about 6 km) ... would be interesting to go Antenworld deep minimg for platinum
... doe, not white TNT cratering.
