Oceanographer Victoria Orphan’s dream was coming true. She was sitting in the Alvin submersible, on one of its deepest science dives ever. But the trip was anything but smooth sailing. Victoria takes us inside the sub, where her dream turns nightmarish as things start to go wrong, and Alvin pilot Nick O’Sadcia works frantically to troubleshoot. Oceanographer Shana Goffredi, who’s also Victoria’s wife, tells us about the tense scene unfolding on the ship miles above, as they wait for word from the sub.
