Some players suggested that you should separate the research
facility from airbase or attack base as to minimize loss of
research against alien retaliation raids which destroy the base.
Transfer objects to be researched is CHEAP, and you only need ONE
of the objects to research.

3.2.6 Manufacturing / Engineering Facility
You just need living quarters and workshops for the engineers,
and general stores for storing the results, and maybe a hangar if
you are manufacturing crafts. Transfer between bases are cheap,
and you don't need anything else. A nice place to put this is
Antarctica.

3.3 Base Design and Expansion
Bases are the guts of X-COM defense. You must build them carefully to
minimize risks and maximize benefits.

3.3.1 Plan for defense!
Try to isolate hangars and access lifts from the rest of the base
to create a choke point. For example:

Design A Design B
HHHHHH HHHHHH
HHHHHH HHHHHH
A X
X XXXX XXXXXX
X XXXX X XXXX
XXXXXX A XXXX H=Hangars A=Access Lift X=anything else

Design A: Vulnerable areas are concentrated to ONE part of the
