And are there any witnesses to Capera's claim that this was all agreed to?
Not trying to stir the pot but this is all one sided at the moment.
Your question is completely valid.
From the start, our duel was based on him challenging me and allowing me to choose the aircraft. When I saw that his name included "Baron," I assumed he had some connection to WWI aviation, just as I do, since I come from a WWI flight community. So, I chose a WWI aircraft. However, as I mentioned earlier in this post, he protested, claiming it was unfair when I picked WWI.
That disagreement was what delayed our duel. Today, I agreed to a WWII match and clearly laid out the terms: Spitfire 1, 5,000 ft, sector 7.10.1.
As per the film..... he "chose" to show up in the 109K-4
