    Dear All,

    As I told you, from China my means to find information are really limited...therefore I'm on this forum for some help.

    My question is:
    What are the modification (structure, armament, engine,...) making a change of version of the Boeing B-17 Flying fortress.
    Y1B-17, to Y1B-17A, to B-17B, to B-17C, to B-17D, to B-17E, to B-17F and to B-17G.

    Thanks in advance

    Philippe
