I had good fun at the coin show and even brought home some new pieces. I wrote about one, the 2014 Centenary of & Submarines , here: https://coinofnote.com/2014-centenary-of-military-aviation-submarines-pnc/ A PNC with two coins to celebrate two centenaries!
Did you know that the first was built in 1620?

📌 Google Research, American Airlines, and Breakthrough Energy have collaborated to develop maps for contrail formation (the white trails seen behind flying airplanes) using artificial intelligence based on such as satellite images, meteorological data, and flight paths.

🤔 How could the use of contrail maps evolve in the field of navigation and air traffic policies, and what work, economic, social, and environmental challenges might emerge from this evolution?

🤔 What could be the consequences of using in reducing contrail formation on potential climate impact disparities among different airlines or regions of the world?
