First off welcom,e to ATS...
It seems logical to me that you would put your best abd most expensive birds underground for maintainence and storage. This makes them pretty hard to
hit and damage.
It would be a fairly simple matter to construct an underground hangar as well. Dig a real big hole and concrete it in the fashion needed to house the
aircraft and work areas.
The elevators needed for going into and out of the underground hangar have been in use on aircraft carriers for years. Pretty much "off the shelf"
all the way round.
Additionally, it makes for a great place to work on new birds that you don't want anyone to see.
PEACE...
