Original Note:
There are several free apps to identify planes in the sky above you. Passenger planes all have jet engines that produce water vapour as a product of combustion. When this condenses it produced contrails (condensation trails). https://www.yahoo.com/lifestyle/identify-planes-sky-120001047.htm https://cimss.ssec.wisc.edu/wxwise/class/contrail.html
