All Electrical Aircraft Delivered

The problem was recently mentioned here, is it practical to have all-electric commercial scale aircraft?  Here a first test underway:

NASA takes delivery of first all-electric experimental aircraft   by NASA in Techexplore

The first all-electric configuration of NASA's X-57 Maxwell now is at the agency's Armstrong Flight Research Center in Edwards, California.

The X-57, NASA's first all-electric experimental aircraft, or X-plane—and the first crewed X-plane in two decades—was delivered by Empirical Systems Aerospace (ESAero) of San Luis Obispo, California on Wednesday, Oct. 2, in the first of three configurations as an all-electric aircraft, known as Modification II, or Mod II.

The X-57's Mod II vehicle features the replacement of traditional combustion engines on a baseline Tecnam P2006T aircraft, with electric cruise motors. The delivery is a major milestone for the project, allowing NASA engineers to begin putting the aircraft through ground tests, to be followed by taxi tests and eventually, flight tests.  .... "
