Dobson Override

The Dobson Override Device was a remote device created by defense department contractor McLennan-Forster to enable the government to control and shut down all of the United States' nuclear power plants.

Unfortunately, during the events of Day 4, this device was stolen by militant Islamic terrorists and was used to attempt to melt down every nuclear reactor within the United States. CTU was able to stop all but one plant (located on San Gabriel Island) from melting down.

The device was eventually confiscated by Jack Bauer while he attempted to capture the terrorist leader Habib Marwan.
