Pilot is dead, but script say he is alive

[kiptanoi 10]

I use this a trigger to go to this file if plane is shoot down.

Plane1Down.sqs

~10
; hint "plane is down";

marker = createMarkerLocal ["obj5", position plane1];
"obj5" setMarkerShapeLocal "ELLIPSE";
"obj5" setMarkerSizeLocal [300, 300];
"obj5" setMarkerColorLocal "ColorRed";
"obj5" setMarkerBrushLocal "SOLID";

;Create Objectives 
obj5 = player createSimpleTask ["Find crached plane"];

;Objectives Description
obj5 setSimpleTaskDescription["<marker name='obj5'>The plane crached in this area.</marker>", "Find crached plane", ""];

;Lets player see sign on screen
[objNull, ObjNull, obj5, "CREATED"] execVM "CA\Modules\MP\data\scriptCommands\taskHint.sqf";
;Set current markerposition
obj5 setSimpleTaskDestination markerpos "obj5";

All is fine there...

Then next step is a trigger to know if I am close to the plane, and when I am that this file is next.

Plane1Found.sqs

if (alive pilot1) then 
{
; hint "pilot is alive";
marker = createMarkerLocal ["obj6", position pilot1];
"obj6" setMarkerShapeLocal "ELLIPSE";
"obj6" setMarkerSizeLocal [200, 200];
"obj6" setMarkerColorLocal "ColorRed";
"obj6" setMarkerBrushLocal "SOLID";
DeleteVehicle checkpilot1;
deleteMarkerLocal "obj5"

;Create Objectives 
obj6 = player createSimpleTask ["Find pilot"];

;Objectives Description
obj6 setSimpleTaskDescription["<marker name='obj6'>Pilot location</marker>.", "Find pilot", ""];

;Lets player see sign on screen
[objNull, ObjNull, obj6, "CREATED"] execVM "CA\Modules\MP\data\scriptCommands\taskHint.sqf";

;Set current markerposition
obj5 setSimpleTaskDestination markerpos "obj6";

; Objective complete
"obj5" objStatus "DONE";
obj5 setTaskState "Succeeded";
"obj5" objStatus "Succeeded";
} 
else 
{
; hint "pilot is dead"; 
DeleteVehicle checkpilot1; 
deleteMarkerLocal "obj5"; 
; Objective complete
"obj5" objStatus "DONE";
obj5 setTaskState "Succeeded";
"obj5" objStatus "Succeeded";
};

Now here is the problem

I got the same message all the time. that the pilot is alive..

But I can see the pilot is not eject when he shoot down.

And script create a marker at pilot position, and I go there..

Then this sctipt is going in.

Pilot1Found.sqs

if (alive pilot1) then 
{
; hint "pilot is alive";
[pilot1] join player;

;Create Objectives
obj7 = player createSimpleTask ["Take pilot with you"];

;Objectives Description 
obj7 setSimpleTaskDescription["You need to take that pilot with you.<br/>", "Take pilot with you", ""];

;// Lets player see sign on screen
[objNull, ObjNull, obj7, "CREATED"] execVM "CA\Modules\MP\data\scriptCommands\taskHint.sqf";

; Objective complete
"obj6" objStatus "DONE";
obj6 setTaskState "Succeeded";
"obj6" objStatus "Succeeded";
} 
else 
{
hint "pilot is dead";
DeleteVehicle checkpilot1;
deleteMarkerLocal "obj5";
; Objective complete
"obj6" objStatus "DONE";
obj6 setTaskState "Succeeded";
"obj6" objStatus "Succeeded";
};

Now... problem is as I say, I got the message that the pilot is alive, and I got a marker and a position and so on... even that there is no pilot alive...

And when I go to this location there is no pilot at all there.

So what is wrong?
