This issue: "The Airlords of Han: Part 1 (of 2)!" Wilma Deering has been sent as an envoy to the city-org of Han, but she hasn't returned... and Han is causing trouble. In order to get "aboard" the hovering city-state, Buck has to ally himself with Black Barney, an air-pirate who trades regularly with the Han, but Barney is playing both sides... what could possibly go wrong? This, that, and everything, that's what!
