The NASA and Lockheed Martin team behind the X-59 Quiet SuperSonic Technology (QueSST) have recently removed the aircraft from its jig system, or external supports. The next step is proving the research aircraft is structurally sound and ready for final assembly.
The team has made significant progress on the X-59 QueSST assembly. In late October, they pulled the aircraft away from the jig support system. The jig, which is similar to scaffolding, helped ensure all of the aircraft's hardware was placed together correctly throughout the manufacturing process.
"It's pretty simple to move the jig away," said David Richwine, NASA's X-59 deputy project manager for technology. "It's the preparation that's more time consuming."
Most of the preparation for the X-59's construction involved more than a decade's worth of research on quiet supersonic technology. NASA's quiet supersonic mission plans to bring all of the science and technology developed during those years into the spotlight.
For Richwine, seeing the construction of the aircraft feels personal.
"I have been working on supersonics technology, and the predecessor to the concept for the past 15 years," Richwine said. "I have more of an emotional attachment because I have put so many years into this mission."
Initial construction of NASA's X-59 began in 2018 at Lockheed Martin's Skunk Works facility in Palmdale, California. The X-59 will be flown as part of a mission to collect data on quiet supersonic flight and public reactions to supersonic "thumps". The plane is shaped in a way that reduces a sonic boom typically associated with supersonic aircraft to a quiet sonic thump to people on the ground. The mission's findings will be sent to regulators to help create new rules regarding speed limitations on supersonic flight over land.
Now that the X-59 is free from the jig, it will move on to the final assembly phase, including the first "power-on" of the aircraft to test its internal systems. Once that is complete, the X-59 will be shipped to Lockheed Martin's facilities in Fort Worth, Texas, where structural tests will be conducted. The first flight of the X-59 is planned for 2022.

FedEx relocates pilots from Hong Kong over city quarantine rules
Hong Kong (AFP) Nov 17, 2021
Global delivery giant FedEx said Wednesday it was closing its crew base in Hong Kong and relocating pilots overseas because of the city's strict anti-coronavirus measures. The move is the latest blow to Hong Kong's reputation as a global logistics hub as strict travel curbs and mandatory quarantine rules keep the city cut off from the rest of the world. "As the global business environment continues to evolve and with the pandemic requirements in Hong Kong, FedEx has made the decision to close it ... read more
