The discovery of Herbig-Haro (HH)-like jets emanating from the high-luminosity young stars LkH-alpha 234 and AFGL 4029 is reported. Both jets are associated with high-velocity molecular outflows. The LkH-alpha 234 jet lies along the symmetry axis of a recently discovered molecular cavity with LkH-alpha 234 at its apex. The AFGL 4029 jet has at least two radial velocity components, one of which reaches velocities of up to - 500 km/s. A proper motion study of the HH objects in NGC 7129 is also reported. It is found that the collinearity of the HH objects with LkH-alpha 234 is merely fortuitous. Alternative sources are suggested. 27 refs.
