What is another word for condensation trail?
Pronunciation: [kɒndɪnsˈe͡ɪʃən tɹˈe͡ɪl] (IPA) 
A condensation trail, also known as a contrail, is a visible cloud-like trail left behind by aircraft engines. However, there are several other terms used to describe this phenomenon. These include vapor trail, exhaust plume, jet trail, aircraft-induced cloud, and skywriting. The term vapor trail is commonly used to describe these trails, as they consist of water vapor that condenses and freezes in the cold atmosphere. Exhaust plume is another synonym, which is derived from the exhaust gases released by the aircraft engines. Jet trail and aircraft-induced cloud are self-explanatory terms used to describe the trails. Lastly, skywriting is a term used to describe contrails intentionally created by specialized airplanes to write messages in the sky.
