Narrative:
The 319th bomb wing was in an exercise preparing for an ORI, and had just completed the flight phase of the inspection.
Postflight maintenance of a fuel transfer valve 29 fault was improperly performed. The valve was popping circuit breakers and technicians were performing fault isolation. The valve was energized in a nearly empty fuel cell. Technicians were continually resetting the breaker. The valve motor ignited the explosive fuel vapor in the tank. The explosion broke the bombers backbone. The forward fuselage fell onto the ground cutting off the crew exit. The maintenance crew inside was trapped as the remaining fuel burned.The plane melted with only a skeleton remaining, and the empenage left standing un marked.
Heroic actions on the part of maintenance crews saved adjacent planes from burning. Additional egress training was given to enlighten crews about alternate egress hatches and ropes in the B-52.

Maintenance crew:

A1C Michael McDonald
Senior Airman Robert Gray
A1C Anthony Salva
Senior Airman Scott Wicik
A1C Robin Rise (the only woman)

Eight others were injured

Sources:

I was performing avionics maintenance on 6507 that morning. I had just left the aircraft to pick up a radar altimeter for 6507. I was delayed in the shop as the technician screwed the lid onto the unit.
Job control had listed me as onboard the aircraft when it exploded.
They were in the process of calling my wife, when I intercepted the radio call to the maintenance supervisor, as we were on the ramp awaiting the fire departments final extinguishing of the fire.
The fatalities consisted of an instrument/autopilot, 2 fuel cell and 2 crew chief technicians.
