The Kaktus Digital Ecoliner Y3 is a fictional aircraft concept of the Boeing Y3 by Melbourne-based artist Harry Lam. Some aviation enthusiasts have confused this fictional concept as an actual Boeing Y3 concept that will replace the 777-300 and 747 product lines as part of Boeing's Project Yellowstone.
