the alert as he monitored his state-of-the-art vessel.
When he reached 10,928 metres into the Challenger Deep in the Mariana Trench of the Pacific Ocean, Vescovo took 15 uninterrupted minutes to take in the view and the enormity of
Details of the groundbreaking mission in late April were released two weeks later. The entire journey took nearly 12 hours – four hours to descend, four hours spent at the
