Query: Commentary on: "Unconventional elasticity in smectic-A elastomers" by O.
  Stenull and T.C. Lubensky   The reorientation behaviour of a smectic-A (SmA) elastomer deformed parallel
to the smectic layer normal has been interpreted as a Sm-C like transition by
Stenull and Lubensky. Experiments, however, prove that such a transition does
not occur.
