Although the aircraft itself does not break the sound barrier, some of the air rushing around the curves of its wings goes supersonic.

The New York Times: Cathleen Morawetz, Mathematician With Real-World Impact, Dies at 94.

“Cathleen S. Morawetz, a mathematician whose theorems often found use in solving real-world engineering problems, died on Tuesday at her home in Manhattan. She was 94.

Her death was reported by New York University, where she had been a professor.

Much of Dr. Morawetz’s research centered on equations that describe the motion of fluids and waves — in water, sound, light and vibrating solids. One of her first notable papers helped explain the flow of air around airplanes flying close to the speed of sound.”
