The defense company is building the QueSST for NASA's Low-Boom Flight Demonstration program. The space agency has just confirmed in a press release its continued support of the plane, regarding funding, and established a timeline for the first flight in 2021.

"This aircraft has the potential to transform aviation in the United States and around the world by making faster-than-sound air travel overland possible for everyone," said NASA Administrator Jim Bridenstine.

"We can't wait to see this bird fly!"
