AEROSPACE
AEROSPACE ENGINEERING
COLD AIR. LOW PRESSURE. VIBRATION.
Aerospace teaches that small components fail in cold, low-pressure, vibration-heavy environments; the failure is rarely the obvious one. The seal that hardens at −30°C. The connector that walks loose over an eight-hour profile. The resin that goes brittle three winters in.
"Cold and low pressure find the joint you didn't reinforce."
