Arms Trafficking Air

After Trevor purchases the McKenzie Field Hangar following Nervous Ron, a Cuban 800 is kept inside for Oscar Guzman's air trafficking work. Each session begins when Trevor enters the aircraft and Oscar gives the assignment over the radio. The first two jobs are weapon drops: two packages go to Great Chaparral near Route 68 and the Altruist Camp, then three go to eastern Mount Josiah, a Grand Senora Desert farm and the Land Act Reservoir in the Tataviam Mountains. Trevor returns to the McKenzie Field Hangar after each flight.

The work then shifts to bombing rival operations. Trevor attacks four Aztecas groups near the Alamo Sea, the Great Ocean Highway, northeast of Paleto Bay and the San Chianski Mountain Range. He next destroys Marabunta Grande cargo being carried by train around Sandy Shores and by boat near Raton Canyon. In the final assignment, Rednecks occupying Sandy Shores Airfield are targeted, with two lines of planes and a line of trucks destroyed by chains of bombs.

All five assignments start and finish at McKenzie Field Hangar in Blaine County, with Trevor landing the Cuban 800 back inside the hangar after completing Oscar's objective. Once the series is complete, further air trafficking jobs remain available from the airstrip in a random order.
