| Terminal flash | |
|---|---|
| Observation | Yes |
| Remarks | The night was foggy, but a group of us looked up upon seeing a series of rapid, white flashes reminiscent of lightning and hearing what we thought was thunder. Directly above us and passing west to east was a bright streak of white that was throwing off smaller sparks of white in trails. We could not distinguish any remaining trail, but the night was shrouded in full cloud cover and fog. To reiterate, the flashes and fragmentation were bright enough to see clearly on a night with 100 percent cloud cover. At the end of the streak, which seemed to pass many miles to the east, the object disintegrated totally into a spectacular flash of white. |
| Fragmentation | |
|---|---|
| Observation | Yes |
| Remarks | We saw repeated, rapid white flashes much like lightning. Then, looking up, we saw a white, sparking, flashing streak sending off staccato yet random flashes as pieces visibly fell away in white explosions. |
