Ive just finished reading through this thread... this is absolute madness at its finest. Absolutely jaw dropping attention to detail.
Now while obviously a b17F, when I was a boy they gave studio tours at Movie World on the Gold Coast. Part of that was a Memphis Belle experience, if you will. They operated a scale studio model which must have been around 1/20. Props spinning, all the turrets moved and fired! Large muzzle bursts streaming out of everywhere. I would love to know how they achieved that.
Its always left an impression on me so to see you creating this work of art, gives me no end of enjoyment!
