Aces High BB - Historical Accuracy of Skins
This thread has someone who claimed to have flown the collings version and talked with the crew of the real deal -- he says the artwork shoudl be on one side, which I guess makes sense as it is hard to imagine them taking the time to paint something that elaborate on both sides of a huge plane like that in the middle of a war!
Strange too as I read posts saying the bird crashed before returning to the states and was totalled, and another saying it returned to the states only to be scrapped immediately at the boneyards.... lots of contradicting info out there on this bird and, apparently, no photos of the left side....
