Haboobs occur regularly in dry land area regions throughout the world. During thunderstorm formation, winds move in a direction opposite to the storm's travel, and they move from all directions into the thunderstorm.

The scattered formation reached Desert One, 50 to 90 minutes behind schedule. "Bluebeard 2" arrived last at Desert One at 01:00 with a malfunctioning second-stage hydraulic system, leaving one hydraulic system to control the
