A 37-year-old paraglider made a hard landing at the Mokuleia Polo Field at about 10:30 Tuesday morning.  Fire Captain Terry Seelig says the woman was about 25 to 30 feet above the polo field when she came down. She was transported to a trauma center in serious condition shortly after.  Firefighters were already in the area searching for a missing kayaker.  Captain Seelig says the search operations were not affected by the hard landing.
