In yet another exercise of the government's involvement with american's flight habits, I discovered an article this week that outlined just how the feds can keep tabs on people's online habits while flying. This Wired article enlightens us as to what is going on behind the scenes.
Gogo, the company which provides the WiFi service for several flight companies (such as American Airlines and US Airways) actually voluntarily oversteps the requirements in the Communications Assistance for Law Enforcement Act (CALEA), which allows the dreaded NSA to track certain users. There's a defined minimum to which ISPs must aid the NSA, but Gogo actually goes above and beyond to aid the government in keeping an eye on us in the sky.
Privacy advocates are already peeved by CALEA, and are understandably upset by this overstepping. Wise users who are concerned about shadowy entities looking over their shoulders advice setting up a home VPN through their home routers in an attempt to make spying more difficult.
