It has long been clear that steady, single-velocity jets should not have discernible features, in conflict with the VLBI data that first suggested parsec-scale relativistic outflow! But in 1984, aside from 3C345, there were few detailed studies of velocity fields in jets on any scale: little was, or could be, said at Green Bank about jet velocity fields. In contrast, this meeting saw good evidence for, and explored consequences of, velocity fields in jets over a wide range of scales.
