Seawulfe - you and Deja need to start a new club.
Call it "the we are mad club."
Or better yet, "the are mad, and we didn't read the posts before we starting acting imperious club"
2x in the past 2 days I have seen one of you try and squeak raub out for agreeing with you.
That said:
I thought about what was posted, and I think you have a point, but I find the screens odd. Here's why:
The dora has a longer tail section. Given the same height in landing gear, this would make the angle between the ground and the gun flight path smaller than on the A8. This is simple geometry. Then I checked a book, and the A8, at 3.96m, is actually noted to be taller than the Dora at 3.36m, which would increase this effect even more.
This would make the dora shoot further under the camera, and decrease the impression of dispersion, while the A8 would be shooting more directly at the camera and enhancing the effect.
In these screenshots, the exact opposite is happening, which is very odd. You could factor in the angle of the ground, except that the camera view is based on the aircraft in relation to itself - not in relation to the ground...
So...
I'd say we need to test some more.
Perhaps some films of the two aircraft in level flight firing their guns, which could then be paused and viewed from different angles are in order.
