While on a trail in northeastern France in 2020, a hiker found a 110-year-old carrier pigeon bag. He spotted a two-inch-long aluminum cylinder half-buried in the ground, and upon investigating, discovered that it contained a note written by a German infantry officer and dated either 1910 or 1916. The message had probably slipped from the leg of the pigeon who was supposed to deliver it. (From Ripley’s Believe It Or Not: Escape the Ordinary)
