So have modified ZaltysZ script, with some damage

, fastes way to ground is to disable all controlls and the engines.
Code:
using System;
using maddox.game;
using maddox.game.world;
using System.Collections.Generic;
public class Mission : AMission
{
public void _DespawnEmptyPlane(AiActor actor)
{
if (actor == null)
{ return;}
Player[] Players = GamePlay.gpRemotePlayers();
bool PlaneIsEmpty = true;
foreach (Player i in Players)
{
if ((i.Place() as AiAircraft) == (actor as AiAircraft))
{
PlaneIsEmpty = false;
break;
}
}
if (PlaneIsEmpty)
{
(actor as AiAircraft).hitNamed(part.NamedDamageTypes.ControlsElevatorDisabled);
(actor as AiAircraft).hitNamed(part.NamedDamageTypes.ControlsAileronsDisabled);
(actor as AiAircraft).hitNamed(part.NamedDamageTypes.ControlsRudderDisabled);
(actor as AiAircraft).hitNamed(part.NamedDamageTypes.Eng0TotalFailure);
//for 2mots
(actor as AiAircraft).hitNamed(part.NamedDamageTypes.Eng1TotalFailure);
//wait 10min
Timeout(600.0, () => {
(actor as AiAircraft).Destroy();
});
}
}
public override void OnPlaceLeave(Player player, AiActor actor, int placeIndex)
{
base.OnPlaceLeave(player, actor, placeIndex);
_DespawnEmptyPlane(actor);
}
}
