"Let's first dispense with the adventure label. Vilhjalmur Stefansson, one of the last great polar explorers, is credited with the definitive statement on this subject. To paraphrase him, adventure is what befalls explorers who fail to properly plan. Like Stefansson, I am not an "adventurer."
Modern, high-tech exploration, which is what I do, is quite different. The objective is to advance our knowledge of the frontiers by bringing back new data in the safest possible manner." Bill Stone
