The book I was reading made a point of explaining it, "los aviones comunes (una especie de ave) chirriaban", which I thought was funny. I guess, if you don't know that this type of avión is a swallow and not an airplane....
It's a bird, it's a plane, it's a.... house martin!
"Sir, you are not allowed to board the swallow without a boarding pass..."
