That's a weak analogy. More like "The cost of an accident, should one occur, could be extremely high in terms of human life and the risk is completely avoidable

That's a weak analogy. More like "The cost of an accident, should one occur, could be extremely high in terms of human life and the risk is completely avoidable in that no one absolutely needs to eat meat in flight, they can eat vegetables." If that was scientifically plausible, I'd be happy to eat my broccoli in flight.
