As usual, more than one way.
Using Layer Masks
1. Duplicate the layer
2. Hide the lower layer by using the eye in the Layers dialogue
3. Add a Layer Mask to the top layer, default white.
4. Make the background of the top layer transparent by painting with black on the Layer Mask
5. Use eye to make lower layer visible again.
6. Adjust colours of each layer as required
7. No need to merge, Save as xcf keeping the layers intact.
Using Paths
1. Use the Path Tool to trace the outline of the plane
2. In the Paths dialogue, use the Path to Selection icon to create a selection on the plane
3. Copy the selection; Paste as a new layer above the original image.
You now have the 2 layers that can be adjusted separately.
