Gliders or Paratroop transport?

[iCaMpWiThAWP]

I played around and found out that gliders count as destroyed vehicles enven when they land OK, and i lost a mortar in a heavy landing, into a stone building gliders have the advantage of bringing equipment that is really iomportant, i landed some bazookas in the enemy's rear and struck their TDs, before my land forces could get to the objectives, the only enemy units were routed infantry and crews, oh, and when a plane/para transport/glider gets shot down is there a chance that its crew/cargo survives?
