| Persistent train | |
|---|---|
| Observation | Yes |
| Duration | 30s |
| Length | 15° |
| Remarks | Photo submitted was of smoke train. Moving too quick to attempt to photograph actual fireball. Just enjoyed the view for 2-3 seconds, then photographed the smoke train at least 10 seconds after the fireball. Estimate smoke trail was visible for at least 30-45 seconds, but started to dissipate and became "wavy" in nature quite quickly. Was photographed from the cockpit of a Boeing 737 at 35,000 feet, on a course of 170 degrees magnetic, at a lat long of N47.4271, W113.0036 (GPS estimate +/- 30 seconds at ground speed of 500 knots). I was unable to enter a lat long at my initial position estimate on the first steps here, so I did my best to approximate, but the lat long is much more accurate obviously. |
| Terminal flash | |
|---|---|
| Observation | Yes |
| Remarks | At least one bright flash, possibly two. Unsure of fragmentation, if so it was not clear. My estimate for luminosity was conservative in nature, the flash itself was many orders of magnitude brighter than the trail itself. Definitely erratic in nature, 100% not a contrail (I am an airline pilot). The first flash was bright enough to catch my attention while looking inside the cockpit, out of the corner of my eye and at the upper edge of the cockpit window. |
