The next step in the process is getting both wings together so that the back end of the vehicle will be complete.
Firstly, capping off the top of the central section that will hold the wings together so that it will adhere to the wings better. Here you can see it half open. The other half of the top is also glued on.
Then the wings are glued to this joining section along with some pins through the center to provide some extra stability. The top section then has an additional piece of plasticard placed on top to help hide the join and contribute to the overall curve and downward slope of the wings.
