Terminal velocities for stellar winds in intermediate and high galactic latitude OB stars have been determined from high resolution IUE ultraviolet spectra. These velocities, together with previous estimates, have been used to deduce stellar masses which are found to be similar to those derived from conservative and non-conservative evolutionary tracks for Population I stars. It is therefore concluded that the stars are not subluminous, nearby objects but are normal and at the large z-distances calculated by previous authors.
