A striking feature of extragalactic radio jets is that they are so narrow. Theories of collimation should account for opening angles of order 1° or less (as opposed to those of laboratory jets which become turbulent and typically open up to more than 10°). This makes instabilities particularly troublesome for theories of collimation in which they are present. While instabilities might not entirely destroy the general bipolar nature of the flow, they decollimate it by definition.
