Link: Helmet fire – Wikipedia

"Helmet fire" is an expression for a mental state characterized by unnaturally high stress and task saturation and loss of situational awareness. The term originates in the military pilot community: military pilots are trained in high-performance aircraft and wear helmets to protect their cranium and muffle out engine and wind noise. A fire aboard any aircraft is considered a serious emergency, and the term helmet fire is used jokingly to say that the pilot is undergoing so much stress that his brain is on fire or smoke is coming out of his ears.
