A Quiet Supersonic Jet Is In The Works As Predicted Thousands Of Years Ago 605 B. C.

 But thou, O Daniel, shut up the words, and seal the book, even to the time of the end: many shall run to and fro (Jet Travel?), and knowledge shall be increased (Internet?).

NASA is working on developing a next-generation supersonic jet that can break the sound barrier with a soft "thump" instead of a sonic boom. 

They are using a technique called schlieren imagery to "visualize supersonic flow phenomena with full-scale aircraft in flight" with the sun as the backdrop for the photos.

 According to a NASA blog post, viewing shock waves and their density is crucial to the project so engineers can work on a design to minimize those reverberations. 

While the Quiet Supersonic Technology (QueSST) research aircraft is being developed, stunning images were captured of a supersonic jet flying at Mach 1.05 with the sun in the background. 

 NASA says when QueSST is operational, it could "unlock the future to commercial supersonic flight over land," essentially ushering in a new era of aviation that could allow us to get from point A to point B faster and without the loud roar of the Concorde as it breaks the sound barrier.
