yeah.
How long do they let you out each day?
Airplanes would be an incredibly inefficient way to brainwash the people. Why not just put the brainwash stuff into the water supply? Everyone drinks it, and it's much easier, cheaper, and reliable to distribute that way. Plus, there's no visual evidence as there is with this chemtrails crap.
As for government brainwashing with TV. Nah. They're doing it through the public education system. Reference Minnesota's recent poly sci fight in which teachers had to fight the new social studies standards that emphasized how good America is and de-emphasized the stuff we've done wrong (slavery, oppression of the indians, etc)
