improvement

Exploration Stage: Crash Site
From: Detective
Description: For Case to escape the agents and reach the city of shadows, he would have had to build something out of the ordinary, something amazing. An enclosed cabin? Automated driving? Without that kind of improvement, you can't push the limits of humanity, man. Can you find me some kind of improved model?
Completed: Based on this model, wasn't the largest and fastest airliner that Case was going to build in the first place? But in the end, he poured all that experience into assembling an aircraft that would take him to the shadow city.
