The plane carrying Huhn's body is expected to touch down at Capital City Airport Friday night at 10. It will then be taken by police escort to Portland's VFW post.
It will then be taken by horse-drawn carriage to a funeral home about a mile away.
Residents in the area are encouraged to line Bridge Street in Portland for a luminary procession. It is set to start at about midnight.
Churches in the area, and the VFW post, are open to keep people warm while waiting for the procession.
