Remarkable NASA photo captures U.S. civilian jet breaking the sound barrier: "Makes the invisible visible"

A little over a month after a civilian jet broke the sound barrier, Boom Supersonic and NASA have released a photo of one of the aircraft's historic test flights over the Mojave Desert.

The image released Monday shows the XB-1 aircraft, which Boom Supersonic said is the "first civil supersonic jet made in America," during its second supersonic flight on Feb. 10. The company said it partnered with NASA using a technique known as Schlieren photography to visualize what can't be seen with the naked eye.

"This image makes the invisible visible," Boom Supersonic founder and CEO Blake Scholl said in a news release.
