Around 9:00, flames erupted from the open hatch, with smoke variously described as "a pretty gold, yellow color" or as "orange smoke in the morning sunlight...beautiful to see." Twelve minutes later, the Grandcamp disintegrated in a prodigious explosion heard as far as 150 miles distant. A huge mushroom like cloud billowed more than 2,ooo feet into the morning air, the shockwave knocking two light planes flying overhead out of the sky. A thick curtain of steel shards scythed through workers along the docks and a crowd of curious onlookers who had gathered at the head of the slip at which the ship was moored. Blast over pressure and heat disintegrated the bodies of the firefighters and ship's crew still on board. At the Monsanto plant, located across the slip, 145 of 450 shift workers perished. A fifteen-foot wave of water thrust from the slip by the force of the blast swept a large steel barge ashore and carried dead and injured persons back into the turning basin as it receded. Fragments of the Grandcamp, some weighing several tons, showered down throughout the port and town for several minutes, extending the range of casualties and property damage well into the business district, about a mile away. Falling shrapnel bombarded buildings and oil storage tanks at nearby refineries, ripping open pipes and tanks of flammable liquids and starting numerous fires. After the shrapnel, flaming balls of sisal and cotton from the ships cargo fell out of the sky, adding to the growing conflagration.
The sheer power of the explosion and the towering cloud of black smoke billowing into the sky told everyone within twenty miles that something terrible had happened. People on the street in Galveston were thrown to the pavement, and glass store fronts shattered. Buildings swayed in Baytown fifteen miles to the north. The towering smoke column served as a grim beacon for motorists driving along the Houston-Galveston highway, some of whom immediately turned toward Texas City to help. In Texas City itself, stunned townspeople who started toward the docks soon encountered wounded persons staggering out of the swirling vortex of smoke and flame, most covered with a thick coat of black, oily water. many agonizing hours were to pass before a semblance of order began to replace the shock and confusion caused by this totally unexpected and devastating event....
