The "Shape" of the vapor barrier around the object is the same shape as a chicken egg...the same shapes as a falling drop of water...which is the most aerodynamic...
PS did you know that cracks in breaking glass travel @ the speed of sound...

Google "breaking sound barrier shape"

Also this is an interesting controversy about a cloud shape produced by a jet:

It depends on how the moving object is displacing energy, is it moving in one direction? Is it emanating from an origin?
Directional = Cone
Emanating = Sphere or Ellipsoid (depending on a few factors)

the speed of sound in a liquid? (which liquid, what temperature and what pressure)
the speed of sound in a gas? (which gas, what temperature and what pressure)
the shape of the waves?
the deformation of the object?
are we in an inertial frame of reference?
please include the necessary data when you frame your question
