Operation Blue Skies is Google’s mission to help pilots avoid contrails.

The company calls it the world’s first state-backed trial aimed at mitigating warming contrails across an entire flight corridor — specifically the eastern half of the North Atlantic corridor, which accounts for around 5 percent of global contrail warming. Contrails (not to be confused with conspiracy theories about “chemtrails”) are a big problem for the planet because they trap heat, accounting for about 35 percent of aviation’s global warming impact. Google has been working with American Airlines to help pilots find more sustainable flight paths.
