Last Exile, Kaze wo Mita Shounen Recommendations
Similar alternate world time line involving technology and weapons including airships and open cockpit planes and despotic dictator. TBWStW also has a bit of a "steampunk" feel to it whereas Last Exile is decidedly such. Despite the fantasy aspect of "special powers" The Boy Who Saw the Wind is possibly a bit more realistic than Last Exile. Both are excellent.
