The problem with this is that the punch has to be on that panel for it to have the effect I want. There can be no panel after that panel, or it breaks the flow. The first idea is good, though.
This is a much better idea. I'll probably put one on the inside fuselage somewhere or on hawking's jumpsuit.
Then really you're not very observant. The second panel makes it clear they're on a plane. I did some research and it looks like vomit comets do have windows, so i'll put those in.
