The following config controls the "delay" between the start of the airdrop event (either it is server wide or called in by an user) and the drop of the cargo at the spot. In a nutshell it will make your planes fly must faster aka airspeed.

You can change the duration of the supply signal smoke.

Finally you can also adjust the time it takes for the dropped cargo to reach the ground by changing it's mass and drag values.

"Cargo": {
"Mass": {
"Enabled": false,
"Min": 20.0,
"Max": 20.0
},
"Drag": {
"Enabled": false,
"Min": 2.5,
"Max": 3.5
}
}}[/CODE]
