Not really, though. They're both (retracting the gear, and cutting off fuel) just toggle switches, as far as your brain's conscious mechanisms go. Doing them both on every flight dulls the part of your brain that cares about how they feel different to perform.

(I'm not strongly arguing against the murder scenario, just against the idea that it's impossible for it to be the confusion scenario.)

Neither is a toggle switch and the gear lever is incredibly conspicuous:

This would be like opening your car door when you meant to activate the turn signal.

I meant philosophical toggle switches, not physical ones. The gear can go between down and up. The fuel can go between run and cutoff. Given enough practice, the brain takes care of the physical actions that manipulate those philosophical toggles without conscious thought about performing them.
