I do note it! Note how fragments failed to perforate the thin plexiglass side window by the "Cheek" gun! Note that with the "entire" flight deck "shot away" there are few fragment holes threw the thin skin of the ajaisent fuselage area! Also note the lack of casualties from said hits as stated in your link!
All in all, a very convincing argument for my point of view!
Look closely at the frame and longerons next to the impact site. Note that there appear to be only 3-4 holes in those frames from the detonation. How do you explain that?
Also note that the entire left most portion of the hole was caused by the slip stream tearing the damaged panel from the framing underneath. The forward portion of the hole is from the blast which was trapped between the interior and exterior panels. The weaker panel was torn off and fell away.
Note that if you look closely at the bottom edge of most central piece of torn skin, you can see the entrance hole made by the shell. The lighter colored longeron below it shows through the hole. Note the complete absence of fragment holes in all of the skin panels!
Can any one here dispute any of these claims?
4. Disagree that 12.7mm AP came close to equalling the penetrative power of a 20mm AP at anything like normal combat ranges.
One of my favorite films is of a severely damaged B-17 trundling along with a Bf-110 flying in formation behind and pumping 20 MM shells into it seemingly WO EFFECT!
