“just waiting for someone to come up with a valid explanation for buildings giving magical movement to planes and ships. No one has done this yet.”
Thats the easy part of the problem… centers of logistical support (Rail, Fuel stocks, Quick industrial pathways, established airports that can handle the numbers of planes, centers of trade, population centers of the military industrial complex).
A Batteship cant just park at the Malibu pier and fuel up. If it did , it would have limited range unless Malibu can supply 4 months worth of food, fuel, ammo, etc. It has to go to San Diego or Hawaii, or Puget Sound.
A B17 cant land at Santa Monica Airport and have anything available. It as to go to Paterson, or a military base where an airport with sustainable services exists.
So the real movement of ships is 3, the real movement of planes is +1, the fact that sometimes a Stuka takes off from my driveway, means it has less range than leaving Tempelhof. You and people like you are looking at everything backwards. Planes are being held back in movement and their full capabilities are only seen in terms of range, if they leave an established centre that provides support, parts, fuel, ammo, training, Tikka Masala,etc
Do you not understand now???
