Ferdinando you're right about everything but unfortunately we all were wrong in "glimpsing" on the picture something that does not really exist. What seemed to me a panel and to you a section of the fuselage is in fact only the cockpit overturned on the wing as can be clearly seen in the other photo. Probably both pictures had been taken on the same occasion.
I thought it was a panel because it seemed that the edges were too defined than those of a ripped sheet but as you see the reality is different and I'm sorry I have stirred up all this "hornet's nest".
Among other things I also said another nonsense about the flaps that actually are in the retracted position while the radiator flaps are open and this made me misled.
Sometimes, before starting to write in one go it would be better for me to lose a little more time in observing better and in thinking more.
I cannot understand if it's just because old age or simple stupidity.
Sorry.
