If the blast pattern was radial, then how could this meteor be extremely fast and skimming our atmosphere but not leave an oval pattern?

Also many iron meteorites DO break apart, but size does matter, right?

From my understanding, it's the force of the impact with the atmosphere that can create a fireball and shockwave. The comet may have been mixed with heavier elements as well. I've heard them described as "dirty snowballs".
