X-57 Electric Project Comes To An End NASA was working on an electric aircraft in the background for a while now and just pulled the plug on the project. The NASA X-57 never even made it to first flight before they shelved the program. Towards the end of last month the agency made the announcement that it would be ending the program. They expect to totally wrap-up all work dealing with the aircraft by September. They also want to publish a paper citing the successes and failures of the program.
