During the "Hellfire" scenario, which took place earlier in the incident, Gill was one of numerous firefighters and police officers attempting to coordinate and evacuate civilians from the Apple Inn and surrounding area.
At the crux of the crisis, on October 1st, 1998, Gill and Danny - another surviving 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, likely having already been further out of range.
