 Volunteer pilots for the EAA Young Eagles program fly youth ages 8 through 17 on introductory educational flights for free, and as of late 2013 have flown more than 1,800,000 young people.Several groups' volunteers such as those for Pilots 'n Paws transport animals, such as to distant shelters or new habitats.Note that most of the aircraft are small and cannot cross oceans and in general can't support long international flights.
