Question
What is the deepest man made dive ever made?
Answer
Trieste was a deep-diving research bathyscaphe ("deep boat") with a crew of two people, which reached a record-breaking depth of about 10,900 m, in the deepest part of the oceans, the Challenger Deep, in 1960. The dive has never been repeated, and presently no manned or unmanned craft exists capable of reaching such depth.
