USSR Begins Drilling World's Deepest Hole (1970)

The Kola Superdeep Borehole project was an attempt to dig as far as possible into the Earth's crust. It began when, in 1970, following setbacks in the Space Race, Soviet scientists looked downward. Digging on the remote Kola Peninsula for some 20 years, they reached a depth of 40,230 feet (12,262 m)—about a third of the way through the Earth's crust—before being forced to stop due to higher-than-expected temperatures of 350° F (180° C). Surprisingly, water was found at what depth? More...

The Russians were clearly wasting their time because there was already a passage to the center of the Earth in Iceland. Everyone knows that, don't they? Here's irrefutable proof!

How can 40,230 feet (7.619 miles) be considered "about a third of the way through the Earth's crust" when the diameter of the earth is 41,850,758 feet (7926.28 miles)? Isn't that about 9.6% of the way through?

Here's a discussion about the Earth's crust including its thickness which varies over the continents and ocean floors:
http://en.wikipedia.org/wiki/Crust_(geology)

The crust is 3 to 6 miles miles thick over the oceans, and 20 to 30 miles thick over the continents according to Wikipedia. However thick, it is no barrier to the imagination as demonstrated by Verne's "Journey to the Center of the Earth."
