_speed = 210;
_direction = random 360;
_targetPosition = 
[
    (getPos _targetPlayer) select 0, 
    (getPos _targetPlayer) select 1, 
    _flyHeight
];
_distance = worldSize * 0.75;
_endPosition = 
[
    (_targetPosition select 0) - (sin _direction) * _distance,
    (_targetPosition select 1) - (cos _direction) * _distance,
    _flyHeight
];
_planeClass = selectRandom 
[
    "B_Plane_CAS_01_F",

for "_i" from 1 to (1 + (floor (random 6))) do 
{
    _distance = 4000 + (_i * 400);
    _startPosition =
