  The red hypergiant VY CMa and the more typical red supergiant Betelgeuse
provide clear observational evidence for discrete, directed gaseous outflows in
their optical and infrared imaging, spectra, and light curves. In the very
luminous VY CMa, mass loss estimates from the infrared bright knots and clumps,
not only dominate its measured overall mass loss, but explain it. In the lower
luminosity Betelgeuse, similar mass estimates of its circumstellar
condensations show that they contribute significantly to its measured mass loss
rate. We present new measurements for both stars and discuss additional
evidence for gaseous ejections in other red supergiants. Gaseous outflows are
the dominant mass loss mechanism for the most luminous RSGs and an important
contributor to the more typical red supergiants like Betelgeuse. We conclude
that gaseous outflows, related to magnetic fields and surface activity,
comparable to coronal mass ejections, are a major contributor to mass loss from
red supergiants and the missing component in discussions of their mass loss
mechanism.
