(Newberg, OR)  --  A plane and a helicopter are now involved in the search for a Dundee woman who's been missing for a week.  The aircraft have been donated to assist in the search for 38-year-old Jennifer Huston.  Huston left home last Thursday to run errands, and was seen at a gas station and a Rite Aid before she vanished.  Huston, who has blonde hair and blue eyes, was last seen driving a dark green, 1999 Lexus SUV with Oregon license WXH 011.
