Yes there is aircraft included but not for flying with. Okay you are right, for a beginner this is a bit confusing. The Assets Pack only expands the standard capabilities that would be boring or not really WWII-like without the pack. With the pack you have more possibilities to expand your scenario. However, there are no flyable planes included. You have to buy them in eShop separately. Only the Mustang and the SU-25 is for free.
