Gunsmoke - Jet Contrails
About 3/4 into the first part of the two part episode "Island in the Desert", Marshall Dillon and Newly are searching for Festus in the desert. After following Festus' horse tracks, they both come up to a rise. In the distance in the sky above them, you can see two jet contrails that cross each other to form a V. Highly doubtful in the 1800s.
