We initiated a multi-technique campaign to understand the physics an d properties of the massive binary systemMWC 314. Our observations included optical high-resolution spectr oscopy and Johnson photometry, near-infrared spectrophotometry, and K 0 band long-baseline interferometry with the CHARA Array. Our resu ltsplace strong constraints on the spectroscopic orbit, along with re asonable observations of the phase-lockedphotometric variability. Our interferometry, with input from the sp ectrophotometry, provides information onthe geometry of the system that appears to consist of a primary s tar lling its Roche Lobe and loosing massboth onto a hidden companion and through the outer Lagrangian po int, feeding a circumbinary disk. While themulti-faceted observing program is allowing us to place some constra ints on the system, there is also a possibilitythat the outow seen by CHARA is actually a jet and not a circumbinar y disk.Keywords: stars: early-type { binaries: close { stars: individual (MWC 314) { m ethods: observational {techniques: high angular resolution, spectroscopic
