At about 9 p.m. on March 25, 2021, people from Portland to Seattle saw a slow cluster of bright lights with trails cross the sky, breaking apart as it went, and posted videos of what many took for a meteor shower or a formation of craft. The National Weather Service office in Seattle said that night that the lights were the remnants of a Falcon 9 second stage re-entering; the astronomer Jonathan McDowell confirmed that the stage, left in orbit after a Starlink launch on March 4 when its de-orbit burn failed, had come down at about 04:00 UTC on March 26. Days later a farmer in Grant County, in central Washington, reported to the sheriff an object that had left a four-inch dent in his field: a composite-overwrapped pressure vessel from the stage, which SpaceX identified and collected. It is one of the few re-entries where the identification, the tracking and a piece of the object all came together.

Explanation

The second stage of a SpaceX Falcon 9 that launched Starlink satellites on March 4, 2021, failed to make its de-orbit burn and re-entered uncontrolled about three weeks later. The National Weather Service in Seattle identified the lights the same night, and a pressure vessel from the stage was found on a farm in Grant County, Washington, and recovered by SpaceX.
