Recent spectroscopic observations of the interactive binary SS 433 with the ESO's New Technology Telescope show that the compact object is a neutron star. We note that the huge mass transfer rate (which may well be the reason for the uniqueness of SS 433) suggests that a significant fraction of the mass lost from the normal star actually settles on the neutron star. This may have important consequences for the structure of the accretion disk and for the formation of jets in this peculiar system.
