@amazeifystore: One unit mix-up turned a routine flight into the Gimli Glider. ✈️ Air Canada 143 wasn’t forgotten at the fuel pump. A faulty fuel-quantity system and a pounds-to-kilograms conversion error left the Boeing 767 with barely half the fuel it needed. At 41,000 feet, both engines quit. A powerful reminder: the numbers can be right, but the units still matter. What’s the most important engineering lesson you’ve learned?
