How do I start the plane?

Hint 1 of 7:

Have you gone into the engine room yet?  It's the room where some robots are
pushing a moving picture display.

Hint 2 of 7:

Take a look at the "movie" they're making.

Hint 3 of 7:

It kind of looks like a flying bird, but the motion isn't quite correct.

Hint 4 of 7:

Fix it.

Hint 5 of 7:

Click on the device again and you can then look at the individual pictures.

Hint 6 of 7:

And rearrange them.  When you drag one picture to another, the two will swap
places on the display.

Hint 7 of 7:

The ship will be able to fly once you have the pictures in the correct order,
so that they display smooth motion when played together.
