A-10 Attack!

Aerobatics:
-----------
Once you're this far, you're pretty familiar with the A-10. 
The exercises won't be described in as much detail as 
previously, so make sure you know what you're doing. 
You'll do a loop, an Immelmann turn, a split-S, a barrel
roll, and finally a banked variation of a high yo-yo 
(a more elaborate vertical high-G turn). 
You'll probably need only the last one, plus possibly
the Immelmann and split-S, in combat. They're mostly 
fighter maneuvers, but performing them will help you get 
a feel for what the A-10 is capable of.
All of these maneuvers are entirely optional; you can fly 
the missions without using any of them.
