N2 - We examine the recent claim by Balick et al. that their observations of fast low-ionization emission regions in four planetary nebulae pose serious problems to the so-called fast-bullet model for the FLIERs. Using timescale estimates and the results of existing numerical studies, and from the phenomenology of 11 objects, we conclude that, contrary to the claim made in the above paper, the fast-bullet model remains consistent with observations.
