So Issue 2.
We decided to pick up just before the end of issue one, and that that took place shortly after the main events in issue one. So, they escaped and then ditched their flight ASAP. And now they are lost.
Okay, I have no idea what's going on with that last panel and those empty balloons. We'll have to dig out the original art to see what happened. Maybe you'd like to come up with dialogue for those two lines?
