Bit of a different take on flying this time! I used what I believe to be some kind of valve to create a futuristic fighter jet. I flattened the end connections and cut the wings short to give it a smaller, compact war feel for 16; whereas for 17 I made the 'cut off point' into the engine housing for the wings. I also chose to look down onto the plane and gave it a spitfire vibe.
18 became a jackhammer. How did I come up with this? I have no idea. I did want a third plane but realised that a simplistic approach provided machinery from another perspective.
