Silverfoxdmt73,
I wouldn't particularly recommend the Nautical/Aviation sourcebook - it was the worst GDW Twilight:2000 module produced in my opinion. Dodgy artwork, Dodgy statistics for the aircraft included, and the aircraft listed in the module from memory included some types that were not sensible for T2k and dubious even for Merc:2000, while more obvious types that were more appropriate for T2k were omitted.
Ah, okay. Thanks for the heads-up. I might see if I can find some alternative.
