The aliens of P3X-118 established a foothold situation, or alien incursion, on Earth. Using small electronic mimic devices worn near the throat and the temple, they were able to duplicate the appearance and access the thoughts of SGC personnel. The incursion was averted, and the aliens who did not escape through the gate were killed by a self destruct order from their leader. Several mimic devices were recovered and taken to Area 51 for study. P3X-118 has been locked out of the dialing program, and all access codes have been changed.
