Another way to think of this is that a length of the tube was caught under the lower bead of the tire. As the tube inflated, it pushed the bead up and dislodged it from the rim with the resulting blowout. Operator error is the most likely cause. Always inflate the tube just a little bit before installing to prevent this from happening.
