The Story of the World's Largest Diamond Heist
Read the whole thing:
He took the elevator, descending two floors underground to a small, claustrophobic room–the vault antechamber. A 3-ton steel vault door dominated the far wall. It alone had six layers of security. There was a combination wheel with numbers from 0 to 99. To enter, four numbers had to be dialed, and the digits could be seen only through a small lens on the top of the wheel. There were 100 million possible combinations.
Power tools wouldn’t do the trick. The door was rated to withstand 12 hours of nonstop drilling. Of course, the first vibrations of a drill bit would set off the embedded seismic alarm anyway.
The door was monitored by a pair of abutting metal plates, one on the door itself and one on the wall just to the right. When armed, the plates formed a magnetic field. If the door were opened, the field would break, triggering an alarm. To disarm the field, a code had to be typed into a nearby keypad. Finally, the lock required an almost-impossible-to-duplicate foot-long key.
During business hours, the door was actually left open, leaving only a steel grate to prevent access. But Notarbartolo had no intention of muscling his way in when people were around and then shooting his way out. Any break-in would have to be done at night, after the guards had locked down the vault, emptied the building, and shuttered the entrances with steel roll-gates. During those quiet midnight hours, nobody patrolled the interior–the guards trusted their technological defenses.
Notarbartolo pressed a buzzer on the steel grate. A guard upstairs glanced at the videofeed, recognized Notarbartolo, and remotely unlocked the steel grate. Notarbartolo stepped inside the vault.
It was silent–he was surrounded by thick concrete walls. The place was outfitted with motion, heat, and light detectors. A security camera transmitted his movements to the guard station, and the feed was recorded on videotape. The safe-deposit boxes themselves were made of steel and copper and required a key and combination to open. Each box had 17,576 possible combinations.
Notarbartolo went through the motions of opening and closing his box and then walked out. The vault was one of the hardest targets he’d ever seen.
Definitely a movie plot.
