"Trailblazer was a United States National Security Agency (NSA) program intended to develop a capability to analyze data carried on communications networks like the Internet.
In 2005, NSA director Michael Hayden told a Senate hearing that the Trailblazer program was several hundred million dollars over budget and years behind schedule. In 2006 the program was shut down, after having cost billions of US Dollars. Several anonymous NSA sources told Hosenball of Newsweek later on that the project was a "wasteful failure".
The new project replacing Trailblazer is called Turbulence."
