In October 2021, NASA Administrator Bill Nelson told The Verge in an interview that NASA was “getting ready to fly” the electric X-57. Unfortunately it never will, reports Popular Science:

NASA said today in a conference call with reporters that it would not ever be flying its experimental electric aircraft, the X-57, citing safety concerns that are insurmountable with the time and budget they have for the project. The X-57 program will wind down without the aircraft ever going up into the sky. 

NASA said the fix would take too long to implement, but says the project’s game-changing lessons “have contributed to the industry.” The agency is currently working with Boeing on a more fuel-efficient aircraft design.
