Books in the Prop series

A little airplane named Prop lives by the Caribbean sea. He has to learn how to land on tiny islands with runways in the mountains. Or clinging to volcanoes and sometimes even hidden from view. He becomes so over confident about his abilities that he refuses to take advice from anyone. Until the day he has to make the hardest landing of all. Crash after crash leaves him with a bunch of bruises and a big decision. Can he finally ask for help from an old biplane who lives next door?
