A Russian plane approached its target, flying low over a landscape that was in some places green, and in other places, on fire. When it got close enough, it dumped its cargo of water. The flight is part of an international effort to fight devastating wildfires in Greece. This particular blaze was in Olympia, near the birthplace of the ancient Olympics. Meanwhile, on the Greek island of Evia, the daytime sky turned a dusky orange, as fires ripped through forests and buildings.
