Reminds me of the story of the first crewed submersible to the bottom of the Mariana Trench. During the descent there was a loud boom, like some something massive broke. After recovering from the shock, they decided to continue the dive, because if it was something important, they would have already been dead.
> At 30,000 ft. a sharp crack rang through the ship, shaking it violently. The water pressure outside was more than 6 tons per sqare inch., and even a slight fracture in the hull would have meant certain death. It proved to be only an outer Plexiglas windowpane which had splintered under the pressure. The inner hull remained watertight. "A pretty hairy, experience," admitted Walsh.
