On Hawaii Island the flight program was started by an independent man (Big Island Dog Rescue) who wanted to reduce the Hawaii Island Humane Society's euthanasia rate.  Conflict developed ... they're now in litigation (!) and HIHS refused to allow him to send any more animals to the mainland.  Animal rescue organizations on this island are a very splintered and dysfunctional patchwork system.  I guess it shows the need is far greater than the resources.  http://westhawaiitoday.com/news/local-news/no-kill-equation
