That is great that they are making cost-reducing efforts to restore the 318, but it unnatural to have the 318 propelled in this manner. However I am happy that they are returning it to service.
As for the matter of Goose 7, I believe it should keep its original pierce body because that is the way it has always been. It will be a comparison for future generations to see the original goose bodies compared to the upgraded geese (3, 4, & 5). Also, I believe that it should be preserved in the manner how it wa when the RGS owned her. On the other hand though, I am glad the 7 is being maintained and still exists today.
