Argon gas. No need for hyphenation or second s. Allowed Johnny to unleash. Infinitive, not past tense. Critical mass isn’t something a reactor does. It’s the minimum amount of fissionable material for a sustainable chain reaction. Fission reactors don’t explode when you breach them. If it’s something else, there wouldn’t be anything like a “critical mass” involved at all. Within the cockpit? Nice action, but it’s in dire need of proofreading.
