The U.S. Census Bureau says more than 4 million pets are euthanized each year in America because there’s not enough space in shelters. Here in Knox County, the Young-Williams Animal Center had to euthanize more than 60% of the animals they housed last year. But a national charity with roots in Knoxville is trying to change that. Airplane pilots working for the group "Pilots ‘n’ Paws" donate their planes, time and money to fly these animals to people who want to adopt them. As part of WUOT’s Next Wave Radio Project, Katharine Lusky reports on a program that’s committed to finding new homes for stray animals---no matter how far away those homes might be.
