Watched an episode of Voyage to the Bottom of the Sea. In one day the crew of that sub encountered:

• a collision with a whale,
• being threatened by sea monster,
• the diving bell getting loose,
• overpressure in the ballast tank,
• a smoke bomb,
• a sabatour sending fake radio signals,
• an explosion of the main tank causing flooding, and
• getting hijacked by a duo of criminals, twice.

Not a dull moment on that sub, apparently. 😛
