Default Re: Contrails cannot form into clouds (proof!)

take a look at this picture of B-17s in WWII.

Notice how there are no contrails at all from the lower planes, short contrails from the mid level planes and persistant contrails from the upper level planes.

Were they spraying CO2 back then as well?
