Antimatter Rocks-- A Quick History of Flight #001

When was the first rocket flight carrying Antimatter?

It occurred on September 25, 2006.

The rocket thundered away from Spaceport America, tracked by the White Sands Missile Range radar--which trackes all launches from Spaceport America, and verifies the flight profile altitude.

The spin stablized solid fuel rocket engine shut down prematurely, and the rocket fell back into the desert, accelerating at a rate of 14 feet per second, per second, reaching almost Mach 1 prior to hitting the earth.

Today's question: How far did the rocket burrow into the sandy soil of the White Sands Missile range upon reentry?
