Flying Vechile Collision and Damage problem....

Ok, i cant get collision or damage to work for the flying vehicle datablock, i have all the correct nodes, but it still dosnt seem to work :(

Here is my datablock:

datablock FlyingVehicleData(F16)
{
   emap = true;
   category = "Vechiles";
   shapeFile = "~/data/shapes/f16/f16.dts";
   multipassenger = false;

   density = 1.0;
   
   //Physics
   minDrag =                        15; // Linear Drag (slows you down when not thrusting...)
   rotationalDrag =                 15; // Anguler Drag (dampens the drift after you stop moving the mouse...)
   
   //Speed
   maxAutoSpeed =                   10;
   autoAngularForce =               400;
   autoLinearForce =                300;

    minImpactSpeed        	= 10;      // If hit ground at speed above this then it's an impact. Meters/second
    speedDamageScale          = 1.00;

   cameraOffset = 3.0;
   cameraRoll = true;
   
   // Maneuvering
    maxSteeringAngle          = 3;    // Max radiens you can rotate the wheel. Smaller number is more maneuverable.
    horizontalSurfaceForce    = 20;   // Horizontal center "wing" (provides "bite" into the wind for climbing/diving and turning)
    verticalSurfaceForce      = 20;     // Vertical center "wing" (controls side slip. lower numbers make MORE slide.)
    maneuveringForce          = 6400;      // Horizontal jets (W,S,D,A key thrust)
    steeringForce             = 500;         // Steering jets (force applied when you move the mouse)
    steeringRollForce         = 200;      // Steering jets (how much you heel over when you turn)
    rollForce        		= 10;  // Auto-roll (self-correction to right you after you roll/invert)
    hoverHeight        		= 0.5;       // Height off the ground at rest
    createHoverHeight         = 0.5;  // Height off the ground when created
    maxForwardSpeed        	= 90;  // speed in which forward thrust force is no longer applied (meters/second)

   // Rigid body
    mass                      = 100;        // Mass of the vehicle
    integration               = 1;           // Physics integration: TickSec/Rate
    collisionTol              = 0.6; // Collision distance tolerance
    contactTol                = 0.4; // Contact velocity tolerance

    bodyFriction              = 0;     // Don't mess with this.
    bodyRestitution           = 0.8;   // When you hit the ground, how much you rebound. (between 0 and 1)
    minRollSpeed              = 2000;     // Don't mess with this.
    softImpactSpeed        	= 3;       // Sound hooks. This is the soft hit.
    hardImpactSpeed        	= 15;    // Sound hooks. This is the hard hit.
