26 seconds in on this video you clearly see two fireballs with the second one catching up to and impacting the first one.
    The first one makes a shockwave and area behind it with less air pressure. the shock wave at over 10k mph is like a brick wall and acts like a funnel. Like following an 18 wheel semi truck too close to save gas. when the truck hits its brakes the suv behind it impacts. and kaboom. Meteors donT HAVE BRAKES AND CANT CHANGE VECTORS. So when the first piece is slowed down the following ones catch up.
