Since Eastlund's death last December, Nick Begich, son of a former Alaskan congressman and co-author of the 1995 book Angels Don't Play This HAARP: Advances in Tesla Technology, has led the anti-HAARP crusade. "It's not that I think it needs to be shut down," Begich says. "It needs to be monitored more closely and scrutinized. The government hasn't been up-front about the nature of these programs, and they're utilizing the system to manipulate portions of the environment without full disclosure to the public." He worries that HAARP may be capable of mind control because the waves it produces can exist at frequencies similar to those of human brain waves. Citing Eastlund's patents, Begich also worries that the facility can alter weather. More extreme skeptics, like Jerry E. Smith, author of HAARP: The Ultimate Weapon of the Conspiracy, suspect that HAARP was rushed into completion after the 2005 hurricane season, which included Katrina, to keep the storms from making landfall. Others say it was responsible for the destruction of the space shuttle Columbia in 2003.
