A brilliant fireball and detonations were witnessed by many, and the former was captured on video by a news camera while filming participants
running in the Austin marathon that Sunday morning. At first there was speculation by the media that the event was caused by debris entering
the atmosphere after the accidental and recent collision of two satellites in orbit around Earth, though most everyone in the meteorite community
knew right away this was a meteoric event. As this was a retrograde meteoroid, only very small individuals survived to become meteorites and
very little of this material was recovered in the field (specimens below were recovered only days after the fall before they could be touched
by rain). Click this link for the video footage of this fall in progress. |

When Marc Fries' brother, Jeff, a meteorologist, noted that a dreadful image of space shuttle Columbia's reentry debris cloud was picked up
by DOPPLER and mentioned it to Marc, he soon pursued his instantaneous hypothesis that perhaps a meteoric debris cloud could also be captured
and employed in the subsequent recovery campaign. Some years passed before Marc, with NASA's Jet Propulsion Laboratory, could test his theory
on an actual witnessed fall, and the Ash Creek event of February 2009, proved his case in dramatic fashion. Shown above is one pair of images which
led to the successful and rapid recovery of the Ash Creek meteorite; the top was captured at 7,000 feet and the bottom was captured some three seconds
later at 4,000 feet. This was a remarkable first in the field and will no doubt lead to an increasing recovery rate in the future.
