Arms Trafficking Air are a series side missions featured in Grand Theft Auto V.
Overview
After completing the mission Nervous Ron, The McKenzie Field Hangar becomes available for purchase for a price of $150,000, only while playing as Trevor. Upon purchase, Trevor gains access to the fields hangar, and the Cuban 800 airplane that is inside. When Trevor enters the airplane, he will immediaty receive instructions over radio from Oscar Guzman on what needs to be done.
Arms Trafficking Air missions involve Trevor dropping weapons packages onto designated drop zones, and eliminating competition from competing arms runners. There are a total of five air trafficking missions to undertake. In order to unlock the next one, you must first unlock the one before it. Each air trafficking mission earns Trevor $7,000 before any bonus money is added on.
Each of the five missions count towards one out of fifty-nine Hobbies and Pastimes missions, but they do not count towards the 100% game completion checklist.
