The truest thing in the entire series was the typical Soviet joke:
What's as big as a house, burns 20 liters of fuel every hour, puts out a shitload of smoke and noise, and cuts an apple into three pieces?
A Soviet machine made to cut apples into four pieces.
“Safety Margin” is a nebulous concept for Russians. Look at their subs and spaceships.
