On 20 August 2007, China Airlines Flight 120 landed safely at Naha Airport in Okinawa, taxied to the gate, and then exploded into a fireball that consumed the entire aircraft. All 165 people on board survived. This episode examines how a single loose bolt triggered a catastrophic fuel leak, why modern aircraft engineering bought passengers just enough time to escape, and what the disaster revealed about aviation safety culture. Also on this day: Reinhold Messner completed the first solo ascent of Mount Everest without supplemental oxygen in 1980, pushing human endurance to its physiological edge. Venezuela introduced the bolívar soberano in 2018, erasing five zeros from its currency in an attempt to manage hyperinflation exceeding one million percent.
