DSII: VTOL Damage, Arty Direct Fire, Terrain's affect on GMS

1) When a VTOL gets a damage chit, how is it handled?  The Aerospace 
section states that VTOLs are treated as special ground units.	So 
what happens to when one gets a Immobility result?  Does it drop to 
the ground & become a very under-armored firing platform?  Can it 
still hover?  I also assume that a Damaged result will 1/2 it's 
movement & increase it's range band, as opposed to causing it to break 
off like an Aerospace.	
Just checking to be sure.

2) Does have anyone practical experience with modern artillery? A 
friend & I have been engaged in an on going argument about whether or 
not to allow direct artillery fire.  He keeps quoting that it was 
quite common in WWII.  It keep rebutting that the much longer ranges 
in today's artillery should allow it to avoid being overrun, unless 
something is seriously wrong.  Does modern artillery still perform 
direct fire missions (depress the gun & use the Mark I eyeball for 
aiming)?  In particular, would this be an option if the artillery is 
threatened by enemy troops?

3) Does Hull or Turret down affect GMS fire?

Thanks,
Nils
