Visible crew/equipment: The wires holding Jaws to the magnet are visible.
Visible crew/equipment: As Q stops the Lotus for Bond, the orange car that followed Q off the ferry passes in front of the camera. As it does, the camera and crewman are reflected on the car's glass.
Visible crew/equipment: When Bond arrives at Atlantis, Stromberg asks him to board an elevator. As the elevator starts upward, you can see the shadow of a crew member walking on a walkway behind the open metal shutters to the left of the elevator shaft.
Chosen answer: When the nuclear subs have been destroyed, there's an explosion in the control room, and one of the men cries out "Fuel tank!" Liparus has numerous internal fires raging after the battle with her crew. These uncontrolled fires eventually spread to her fuel tanks and ammo storages, one of which explodes in a huge fireball and finally causes Liparus to sink.
I thought the final explosions that sank the Liparus were deliberate self destruction after completing the mission in an attempt to destroy any evidence, rather like when Bolfeld manually triggers explosives after being thwarted in You Only Live Twice.
Liparus sinks slowly, and that would leave her crew plenty of time to evacuate. Angry and armed crew with a grudge against Stromberg.
