Go to the VisionLab product page
, scroll down to the Proffessional Compositing Toolkit section, and click the animation video button with the meteor. It gives you a bit of a breakdown of the elements that went into the shot.

Basically it was done using a mixture of CG particle effects and stock footage.

As Axeman says, check out the full clip on the Vlab page.
Here's a quick breakdown:
Background - just a simple still image of the forest/field/mountains. Bought from a stock image website.
Meteor 'head' - this consisted of two separate pieces of fire stock footage that were warped, rotated and animated together. Given the extreme trajectory of the meteor, it was a bit tricky to animate as it happens so fast. An angle blur was applied to give it a good amount of motion blur.
Explosion - the impact explosion is simply a bunch of flame stock footage composited carefully behind the trees using an intricate mask.
Impact debris - the dirt spraying up from the impact was created using the particle engine, using small bitty textures and a wide emitter angle and heavy gravity.
Cloud - this was created with the particle engine. It's a very dense, shifting rectangle emitter with conflicting emitter angle and gravity to create that turbulent appearance. It was masked to go slightly behind the closest mountain to create a feeling of depth.
Smoke trail - this was a rectangle emitter particle effect that was then given a high-feathered mask to cut it down to the correct shape. The mask was then enlarged and feathered more to enhance the dissipating of the trail.
Cloud hole - the dark spot in the cloud that appears just before the meteor was created using a grade object placed over that spot and darkened down (with the gamma filter I think).
Impact crater - This was another grade object designed to darken the ground and give it a 'burnt' appearance. Two masks were applied at different transparencies, resulting in the dark inner 'hole' and the outer ring area.
Finally a grade object was applied to the whole effect to grade it all a red, ominous tone to match the lighting coming from the boiling, red cloud.
