Sandia officials tell John Fleck that the R NEP sled test will not be conducted at Sandia:
That has prompted speculation that the Sandia test would go forward. Jeffrey Lewis … discussed the issue most recently last week. If the test is really going to go forward, that’s a story, so I called up the Sandia folks today to check. Their unequivocal and unambiguous answer was “no.” No bunker-buster sled track test planned this year or in any foreseeable future. Period.
A little more backstory from John at the Albuquerque Journal.
