a tomb of unknown soldier or tombs of unknown soldiers should work.
it should be within the policy of not releasing info about people from a business standpoint yet honoring all those that flew here and passed on.
a small area with a monument, maybe tombstones with no names around it. all within the area should be protected both ways by killshooter or bullets and bomb terminate instantly within the area. maybe like a cone shaped force field.
maybe located on an island with maps with large body of water, or a high mountain top on maps without large body of water. maybe with names like moutain of the unknowns, or island of unknowns.
maybe some of the mapmakers can spare some time and create something the size of a large airfield that could maybe be added on to the terrains.
