Diver Jeanna Edgerton and her husband Brian Wiederspan describe in detail one of the most intense scenes of the series. After surfacing in a dome with “bad air”, Jeanna struggles to stay afloat and is deprived of oxygen. Brian and the rest of the team quickly mobilize to come to her aid during a very tense, touch-and-go moment.
