Well the 8 F4Fs was easy, I know which of my guys were up.
The 120 Vals came from:
A direct count of the total number of Vals in the squadrons I could confirm were involved based on who we either shot down or were shot down by. This came to about 50-60. The other half was confirmed later on the forum by the Axis CiC for Frame I, who directly acknowledged he sent his entire force of 100-120 D3As to attack Midway.
How'd you miss that thread? It was active for most of the rest of the campaign.
Back to topic:
Lon,
You might turn icons off in film viewer when you take your screens. I find that makes for a nicer image. Also, there's a Field of View problem whenever you set the camera POV too close to the "subject" of the screenshot, and the film viewer is bugged so the FOV slider doesn't work. To get around it, don't use the Up/Down arrows to move the camera closer. Keep the camera back, and use the Zoom function instead.
