@amazeifystore: A tiny worn thread helped bring down Flight 261. ✈️ On January 31, 2000, the Alaska Airlines MD-83’s stabilizer jackscrew disengaged after the threads in its acme nut wore away. Investigators linked the wear to insufficient lubrication and maintenance checks that failed to catch it. All 88 people aboard were killed. Maintenance isn’t paperwork. It’s a safety system.
