The questions themselves have nothing to do with the combatants.
Plus, if you read Darkling Plain you'll understand why the League has any HTA craft.
Speaking of which, here are some pics!
There they are. The airship is called the Sigaw Na Bala, and the HTA craft are, from the left, the Jim Gordon Tigerclaw, Death in a Large Package, and Slag You Newton.
A side-on view of the Sigaw Na Bala.
A head on view of the same.
The Jim Gordon Tigerclaw
The Death in a Large Package
A head-on view so you can see the rocket pod, heavy machine cannon, and the four bombs.
The Slag You Newton. The picture's a bit blurry, but you can see it's an ornithopter, not a monoplane or a glider. It's sole armament is a browning-style drum-magazine machine gun.
The Slag You Newton head-on.
PS about the blurryness, these pics were taken with a webcam, I'm currently having issues with my digi, so you'll have to wait until I can find a decent camera for less than $75.
