In view of the growing interest in the pioneering experiments of J.S. Tsakadze & S.E. Tsakadze [J. Low Temp. Phys. 39, 649(1980)] relating the behavior of nonstationary rotating superfluid helium to neutron stars’’ glitches (sudden jumps in angular velocity followed by a relaxation), we revisit these experiments. We comment on the main results through the lens of our current understanding of superfluid hydrodynamics. In particular, we consider the possibility of a state of quantum turbulence following the initial spin-up of the vessel, and analyze the rotational decay observed by Tsakadze & Tsakadze in analogy with recent studies of quantum turbulence in the two-fluid regime of helium II.
