This never happened. I have no idea how this myth entered the popular consciousness, but it's nonsense.
There was a superstition by pilots that going past the speed of sound was inherently dangerous because of many accidents when planes did go faster.

It is the prediction by the Prandtl–Glauert transformation that infinite pressures would be experienced by an aircraft as it approaches the speed of sound. Because it is invalid to apply the transformation at these speeds, the predicted singularity does not emerge. > The incorrect association is related to the early-20th-century misconception of the impenetrability of the sound barrier.
