The body and tail are cake! Used two 9 x 13, stacked, carved, covered with fondant. Cake ended up being about 22' long. Cake is elevated on landing gear. Landing gear are dowels. Cake is on a 1/2" thick wooden board. Then that board is screwed into dowels(landing gear) that are then screwed into the cake board, which is also a 1/2" thick wooden board. Cake board is covered with fondant and then I airbrushed clouds. I also gave some of the clouds texture. Propellers are NOT edible. They are wood.
