Why do jet planes flying in the sky leave a white trail behind them? 

Asked by Topperlearning User | 3rd Jun, 2014, 01:56: PM

Expert Answer:

When jet planes fly in the sky the moisture from their engines condenses. We then see a white trail of this condensed moisture behind them for some time when there is no air movement to disturb it.
