Remember that flight where the engine caught fire yesterday? That plane made a landing just after takeoff, and all its tiers burst like this.
That's because a plane can't land at full weight that it takes off with. Generally its weight gets reduced as all fuel burns before reaching destination. If that's not the case and a plane has to return to airport just after takeoff -- it has to throw out the fuel in mid air over or near the city, to empty itself and reduce weight before landing. This is called "fuel dumping".
That flight couldn't or didn't do it. The result.
