No luke, you can't just get a old and tired dragon to fly just by telling him to.
you should tie a jetpack on his back. a big one.

Jet packs are good enough for sharks, so they better be good enough for an old dragon!

The bottom row of panels has a layout action flow worthy of the manga itself. That was hilarious.

I don't remember why that couldn't work but that wouldn't work... Any story that the DM forgot the reason why something is not going to work?
