transsonic

By comparison the standard .50 is only accurate to about 1700 yards when the bullet slows to transsonic speeds and loses stability and accuracy.

It has Balanced FlightTM technology allowing the bullet to remain accurate while traveling from supersonic to transsonic to subsonic speeds.

There's some debate whether the aircraft themselves are breaking the sound barrier, or if the condensation effects merely reflect locally transsonic flow (we're talking about a fluid dynamics situation called a Prandtl-Glauert singularity, the clouds being low-pressure regions - thanks to Kentaro Mori for this detail).

The EPL dropped transsonic as the glide slope indicator eased resolutely to center scale.

One was now himself a captive, being borne at transsonic speeds toward the cave where the rogue flexed its new powers, practiced at its new repertory of emotions and grew.

"That yeeking is just the audible edge of their speech; bet we have a lot of transsonic tones in our voices, too."

The pressure drop is an inertial reaction to the pressure jump of having a mass pushing on the air at transsonic speeds.
