En este ejemplo pasamos `Union[PlaneItem, CarItem]` como el valor del argumento `response_model`.

Porque lo estamos pasando como un **valor a un argumento** en lugar de ponerlo en una **anotación de tipo**, tenemos que usar `Union` incluso en Python 3.10.

Si estuviera en una anotación de tipo podríamos haber usado la barra vertical, como:

```Python
some_variable: PlaneItem | CarItem
```
