Breaking The Record
While the Lone Star Producing Company did not find what it was looking for, this was the deepest hole on the planet for five years. A borehole in Kola ended up setting a new record on June 6, 1979. Called SG-3, the nine-inches-wide hole penetrated a cool 39,000 feet into the crust as of 1983.
After That Milestone
After the researchers made this milestone, the Kola Peninsula deep put down their tools temporarily. They stopped working on the site for a year so that other people could pay it a visit. Twelve months after that, they restarted the operation, only to experience a technical issue that made them stop.
