The photographer captured the glowing Mach diamond in the jet's exhaust during the night test.

The Mach angle of the research drone decreased as it accelerated past the speed of sound.

Engineers analyzed Mach angles on the test model to predict shock wave behavior.

During the high-speed dive test, the pilot felt the onset of Mach tuck and had to apply full back pressure to maintain level flight.

During the transonic dive, the test aircraft began to Mach tuck, forcing the pilot to execute an immediate recovery.

As the experimental aircraft accelerated through Mach 0.9, its tailplane lost effectiveness and the plane Mach tucks, surprising the test pilot.

The test pilot tightened his grip when the prototype Mach tucked during the high-speed dive.

The test pilot warned air traffic control that the aircraft was Mach tucking and required an immediate nose-up trim to recover.

The Mach-Zehnder interferometer on the optical bench detected minute phase shifts between the two beams, allowing us to measure a small change in refractive index.

Mach-Zehnder interferometers are essential tools in quantum optics and integrated photonics experiments for manipulating phase and measuring interference patterns.
