How do you use a cargo-bob in gta 5?

To use a Cargo Bob in GTA 5, first, find one at locations like the Los Santos International Airport or Fort Zancudo. Once you have the helicopter, approach a vehicle or object you want to lift, and use the interaction menu (press the designated button for your platform) to deploy the hook. Fly over the target and lower the hook to attach it, then lift off to transport the object. To drop the cargo, simply fly to your desired location and release the hook using the same button.
