This small detail from The Spy Who Loved Me was a nice touch. After all, why would a submarine’s crew voluntarily surrender or open their hatches to an unknown vessel? Stromberg already accounted for that problem. His men use a device that punctures the submarine’s hull and threatens the crew with cyanide gas, turning resistance into a very short-lived option. It’s minor, but I’m sure if it wasn’t addressed nerds like me would’ve asked why the submarine crew would ever open the hatch in the first place.
