Seems to me it'd be a little more realistic if the clouds would actually give us some cover, if we decided to up through them.
ie, Go up through the clouds and nobody below can see your icon. Ahh, but the table has two sides. We wouldn't be able to see the icons below either.
Sure we'd be able to see the planes/dots, from up there, just not the icons right in your face, when you know the enemy is way down on the deck...
FLAME ON! Coogan
