### Setting the globe (the object of which the surface will be used as the height)

main_sphere = bpy.data.objects["Sphere.002"]

### Making the globe useful

origin: Vector = main_sphere.matrix_world.translation

bvh=flight_animation.create_bvh_from_object(main_sphere)

### Setting up world

airport_shader: bpy.types.Material | None = None # Placeholder for shader, can be set to a specific material if needed

flughafen1 = flight_animation.Airport( # Change to Place you want
    name="BER2",
    lon_lat="52° 21′ 44″ N, 13° 30′ 2″ O",
    bvh=bvh,
    origin=origin,
    radius=0.1,
    shader=airport_shader
)

flughafen2 = flight_animation.Airport(
    name="HEL",
    lon_lat="60° 19′ 2″ N, 24° 57′ 48″ O",
    bvh=bvh,
    origin=origin,
    radius=0.1,
    shader=airport_shader
)

flughafen3 = flight_animation.Airport(
    name="NRT",
    lon_lat="35° 45′ 53″ N, 140° 23′ 11″ O",
    bvh=bvh,
    origin=origin,
    radius=0.1,
    shader=airport_shader
)

### Initialize Animation

airplane = bpy.data.objects["Airplane"]
# airplane_vector = Vector((0, 1, 0))  # Setting the airplane default vector (x, y, z)
# reset_object(airplane)  # Resetting the airplane location and rotation

centerjoint = bpy.data.objects["Center_Joint"]
# centerjoint_vectors = Vector((0, 0, 1))  # Setting the center joint default vector (x, y, z)
# reset_object(centerjoint)  # Resetting the center joint location and rotation


### Animation Logic

    math.radians(flughafen2.longitude-90),

]
print("airplane_height:", airplane_height)

travel_height = airplane_height[0] * 1.1 # for 10% extra height in relation to the origin
print("travel_height:", travel_height)

# Set to the Rotation the plane needs to have for the correct rotation at the airport
airplane_rotation = [ # rotate the airplane at the timestamps of the airports !!! Only rotate the z achses in the plane propertys
    math.radians(-35), # rotate so the plane on the first airport so that the front points to the 2nd
    math.radians(-42), # rotate the plane at the second airport so that the back points to the last airport
    math.radians(-111), # like first rotation from 2nd to third
    math.radians(-102) # like 2nd rotation
] #! You do not need more rotation points the rest is done by the interpolation in blender. Maybe you need to set the motion to a constant instead of accelerating and decelerating
