Examples of free noncommutative subgroups of the affine group A(3), which act properly discontinuously on ℝ3, are constructed in the paper. These examples refute a conjecture of Milnor to the effect that the fundamental group of any complete affine locally flat manifold contains a sòlvable subgroup of finite index.
