Technically an overstatement but not by much. Correctly restated, its highly unlikely these actions were confusing pilots. It's as if you mistook flushing your toilet twice when instead you wanted to turn on the lights in your bathroom.

I don't agree with the "twice". A frequently performed manipulation like the fuel cutoff (usually performed after landing) collapses down to a single intention that is carried out by muscle memory, not two consciously selected actions.

Genuinely curious - could heavy marijuana use cause confusion between landing gear and fuel cutoff? Or some other drugs? (Wondering if they screen pilots for alcohol before they board an aircraft.)

The prelim report states these pilots were indeed breathalyzed before takeoff.

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.

That's just your brain associating the bathroom with the act of brushing your teeth, and therefore doing it automatically upon the trigger of entering the bathroom. It bears no resemblance to the accidental activation of a completely different button.

The other poster's correction: "it’s like brushing your teeth with razor" is apt. Touching the fuel cutoff switches is not part of any procedure remotely relevant to the takeoff, so there's no trigger present that would prompt the automatic behavior.

Now I'm trying to remember if I've ever picked up my razor and accidentally begun tooth brushing motions with it. Probably!

More relevantly, you seem to me to be unduly confident about what this pilot's associative triggers might and might not be.

Is cutting off fuel while taking off a better solution than letting them burn?
cjbprime · 2 months ago
Sometimes? If you have enough altitude to trade for speed then after the cutoff you could glide to a hypothetical miraculously-placed runway right in front of you, vs. having fire quickly consume the entire plane if you don't cutoff..

To answer your question: because it is a very rare occurence.
cjbprime · 2 months ago
It's not that rare, and there are institutional factors (such as seeking treatment for psychosis being career-ending for a pilot) that incentivize serious pilot mental health crises being untreated.

If I were to apply OPs assertion to your actions it’s like brushing your teeth with razor. I guess that’s what they meant.
cjbprime · 2 months ago
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.)

There is no possible way to confuse these two actions. There's a reason a wheel is attached to the gear lever.

> There is no possible way to confuse these two actions.

This is obviously an overstatement. Any two regularly performed actions can be confused. Sometimes (when tired or distracted) I've walked into my bathroom intending to shave, but mistakenly brushed my teeth and left. My toothbrush and razor are not similar in function or placement.

One would assume a toggle like that would come with blaring alarms and blinking lights… right? Right??

Edit: It also seems like the engine cutoff is immediate after the toggle. I wonder if a built in delay would make sense for safety.

(Presumably delaying the amount of time before a raging engine fire stops receiving fuel would also have an impact on safety?)

TLDR; If you give the agent an access token that has permissions to access private repos it can use it to... access private repos!?
cjbprime · 3 months ago
It's not that nonsensical. After it's accessed the private repo, it leaks its content back to the attacker via the public repo.

But it's really just (more) indirect prompt injection, again. It affects every similar use of LLMs.
