Would recommend CHS 155 standard campaign scenario, and yes a expansion of ship graphics with some late war aircraft what if's, good game.

Have the Rising Sun boardgame by Clash of Arms, browsing the scenarios.

At Midway 15 B-17E with 17x500-pound bombs attacked the carriers at 6500metres that's around 20,000ft

A classic example The battle of the Bismark Sea.

At low altitude ( 0-100metres )
13 Beaufighters
12 A-20C
12 B-25C-1
6 B-25C

Medium altitude ( 1500-2200metres )
6 B-17E
6 B-17F
12 B-25C

High altitude ( 3000-4000metres )
9 B-17E

Escorts 40 P38E

I don't have any problems with 2E aircraft attacking ships at whatever height one wishes as they will take FLAK, again I'm interested in bombing altitudes of 4E bombers against land targets.
With the Niki mod 2.08b I was using in my game he ( Niki ) stated in the Matrix forums that a bombing sweet spot at 6000ft existed, and a flak gap from 6000 to 9000ft, hence 4E bombers coming in at 6000ft.
But what the hell maybe I'm just a whimp.

Oh just remembered have you seen the RHS mods, terrific satilite maps with a EOS ( what if ) and AI variants for a total of 8 different campaigns.
