40 years ago, April 26, 1986: #Chernobyl nuclear power plant explosion, worst nuclear reactor accident in history. It was caused by an emergency drill gone wrong, an explosion and meltdown. The Soviet Union tried to cover it up until they couldn't 2 days later when radioactivity alarms went off in Sweden. Death toll disputed. The only other major reactor accident since was Fukushima, Japan 2011 due to a tsunami bigger than the plant's tsunami wall. https://en.wikipedia.org/wiki/Chernobyl_disaster #TDIH #nuclear #history

My favourite missions during the first time we went to the Moon were the Gemini Program

via American National Air and Space Museum

'On #TDIH in 1964, Gemini 1 launched on the first mission of the Gemini Program. This uncrewed spaceflight was a test of the Gemini spacecraft and Titan II launch vehicle.'

"Celebrating 100 Years of Liquid-Fueled Rockets" by Air & Space Forces Magazine - Solid-fuel rockets had already been #military weapons for centuries. So it followed that the build-up to WWII saw Axis and Allied powers funding military liquid-fuel rocket development.

100 years ago today, March 16, 1926: Robert Goddard succeeded at the world's first liquid-fuel rocket flight, which lasted 2.5 seconds but proved it was possible. While solid-fuel black-powder rockets had existed for centuries, they weren't reliable enough for more than short-range projectiles or fireworks. Liquid fuel rockets opened the path to spaceflight: first space flight 18 years later in WWII, Apollo 11 Moon landing 43 years later. https://en.wikipedia.org/wiki/Robert_H._Goddard#First_liquid-fueled_flight #rocketry #space #history #TDIH

15 years ago, March 11, 2011: M9.0 Tohoku Earthquake and Pacific-crossing #tsunami caused devastation in northern Japan, a country which is probably the best prepared for quakes and tsunamis. Many cities' tsunami barrier walls were overtopped. Even across the Pacific, one person was washed out to sea near Crescent City, California and his body later recovered near Astoria, Oregon which shows how much ocean currents were disrupted. https://en.wikipedia.org/wiki/2011_T%C5%8Dhoku_earthquake_and_tsunami #earthquake #geology #history #TDIH

17 years ago, January 15, 2009: US Airways Flight 1549 "Miracle on the Hudson" crash, Airbus A320 hit a flock of large birds and lost both engines on departure from NYC LaGuardia Airport.

2 years ago, Jan 5, 2024: Alaska Airlines #AS1282 experienced an in-flight blowout of a door plug on climbout from Portland #KPDX. It returned safely to PDX. But the plane has so far never flown again. Alaska made Boeing buy it back, obviously being defective.

I got this picture this afternoon during a bicycle ride. N704AL is parked on the Boeing ramp by the paint hangar. Plastic sheeting still covers where the door plug has not been replaced. #aviation #business #travel #avgeek #history #TDIH

Because of that quake, all oceans do now. After videos captured widespread tsunami effects, tsunamis went from obscure to well-known.
