Any form of sleep/anaesthesia has a nonzero chance of killing somebody. I don't even want to think what the insurance and liability issues would look like for this. You can say, "well, only if there's a hijacking" and I'll say, "but how could they be 100% sure, and what would insurance companies make them do to be sure before allowing them to potentially kill innocent passengers, with that insurance company liable?"
