In the documentary, Wendy Rush is shown monitoring the mission from the surface when a sharp external noise is heard—later described by a U.S. Coast Guard official as resembling a “door slamming.”

Moments later, a delayed message from the Titan gives the illusion that the crew is still operational, adding to the initial confusion.
