It is noted that planetary nebulae may be destroyed by a snowplow effect as they accrete material during their motion through interstellar space. The scale time for disruption of planetary nebulae with velocities characteristic of the galactic-center population is considered, taking into account mass loss from the central star. The results indicate that planetaries will become optically thin and thus unobservable at radio wavelengths well before deceleration by the interstellar medium becomes important. Numerical calculations show that this will generally occur in less than about 10,000 yr for a 21-cm continuum detection limit of 10 mJy for planetaries with masses of less than about 0.6 solar mass at the distance of the galactic center.
