Abstract
Damour, Deser, and McCarthy have claimed that the nonsymmetric gravita tional theory (NGT) is untenable due to curvature coupled ghost modes and bad asymptotic behavior. This claim is false for it is based on th e incorrect assertion that only non-falling-off solutions can be found for the field equations, and that the nonexistence of an exact gauge symmetry for the skew sector leads to a flux of negative energy. We sh ow that the NGT has solutions compatible with physical boundary condit ions and that the flux of gravitational radiation in NGT is finite in magnitude and positive in sign.
