We consider the problem of motion of several rigid bodies immersed in a perfect compressible fluid. Using the method of convex integration we establish the existence of infinitely many weak solutions with {\it a priori} prescribed motion of rigid bodies. In particular, the dynamics is completely \emph{time--reversible} at the motion of rigid bodies although the solutions comply with the standard entropy admissibility criterion.
