Altitude versus elapsed minutes
The chart reaches 101,260 ft at 79.05 minutes; prose gives 77.6 minutes. Their timing difference has not been silently reconciled.

Vertical velocity versus elapsed minutes
Values reach −92.57 mph; prose states 96.2 mph maximum descent. The poster labels approximately 92 mph. This is vertical velocity, not APRS ground speed.

Acceleration: recorder samples
The clock resets within this series and one sample lacks paired time. Points stay unconnected; no repaired continuous timeline is implied. Source peak: about 6.45 G.

External temperature versus altitude
Minimum is approximately −59.98 °C, consistent with rounded −59.9 to −60 °C prose. Higher-altitude warming is an observation, not evidence of detector-induced heating.

Pressure versus altitude
The chart reaches approximately 49.249 Torr; prose rounds to 49.2 Torr. Altitude is the report’s own channel.

CO₂ channel: lower ascent
Values peak at 640 ppm near 21,874 ft, whereas prose says 21,118 ft. Coverage is roughly 885–41,407 ft. The source’s airline-exhaust explanation remains a hypothesis.

- Acceleration time resets. Points are not joined into a fabricated continuous timeline.
- Particulate and CO₂ records cover lower ascent, to approximately 41,407 ft.
- The November 2024 radiation figure on a later poster is not assigned to this flight. No replacement radiation curve is invented.
