Cargo planes have gotten louder, I swear, as if the new atmosphere were conducting sound a lot better with its new composition. Normally those planes almost couldn't be heard in the past, they were a 'barely audible colorful background noise' at most. Are they flying lower now, because of changed the atmosphere?! Annoying as heck!!Funny you mention contrails, because the last couple of days since temperature dropped here in east Germany we have a lot of contrails!
