On October 1st, 1998, Gill and Danny - another firefighter - flew an RFD-registered helicopter over Raccoon City in search of survivors. Witnessing Nikolai Zinoviev's demolition of the Raccoon University, the two flew over the wreckage to search for people who may have survived the blast. Finding them, it was arranged that the helicopter would land at the university's back square to allow for extraction.
After a showdown with the ThanatosTyrant, the survivors evacuated with Danny and Gill, and the chopper escaped Raccoon City before its destruction. Unlike Jill Valentine's helicopter escape on the same day, they were unaffected by the electromagnetic pulse.
