Photos of persistent contrails date back to the 1930s. People have been noticing them and commenting on them for even longer than that. They are not a new phenomenon but have become more prevalent as air traffic has increased. https://www.metabunk.org/threads/debunking-contrails-dont-persist-with-a-study-of-70-years-of-books-on-clouds.3201/
