My Notes
9:30 “It’s almost impossible to perform a persistent contrail. ..you need unique atmospheric conditions in order to form a contrail, and these conditions are hardly ever present. … You have to be an airplane above 30,000 feet; the temperature has to be below -40°C [or -40°F], and you have to have relative humidity of 67% [or higher].”
15:30 In the fuel for commercial planes and aerosol sprayers on military
Airlines may be involved.
28:15 Weather modification
