I just casually plonked mine in the middle of Europe and I was fine, in my opinion it doesn't matter a lot aside from ensuring optimal, non-overlapping coverage for Hyperwave Decoders in the future
The reason Airbus is shitty beacuse it is supposed shitty. It has a "GET A BETTER CRAFT" painted all over it.
I actually feel like I don't have enough stimuli to upgrade from Airbus to the Pachyderm in particular. Two extra people and finally getting good range just didn't feel that useful for me. (besides maybe for Mansion missions) I wanted to rush to the Skyranger, but I didn't know what research unlocked it, so I spent a very long time in the Airbus until I eventually gave up and got Pachyderm before it took me 2 more eternities to get somewhere. Then the Skyranger was useless because I was able to research Bonaventura almost immediately after I got the ability to purchase it.
