Contrail Science
How Long do Contrails Last?
Q) How long do contrails last?
A) Anywhere from less than a second, up to several hours.
This is an oft-asked question. The answer is reasonably straightforward, but misunderstanding is common. To understand why a contrail can last as little as a fraction of a second, or as long as several hours, you need to understand what a contrail is, and how it forms.
