PHP Designing Interfaces in PHP Introducing Interfaces Define an Interface

Why won't this work?

They said to add methods to my interface.

<?php

interface FlyableInterface

{
  public function takeOff();

They ask you to name your interface "Flyable" not "FlyableInterface"

But first task says well done when you use Flyable Interface and the course guides you to always use the Interface word!? Course video miss leads you

You're right! I changed it to "Flyable" and it worked.
