The log

Other makes of altimeter keep their settings on the device and do not write them into the log, so there are none to show here. This is what the file itself told us.

Files

Where the altimeter signs its log, the file carries that signature and a tick beside it. A tick means the data is unchanged since the device wrote it, which is what a record claim needs.
CSV

The log as columns of text. Opens in a spreadsheet, and in every simulator that reads flight data.

The weather for 48 hours either side of the launch, within 15 km of the launch site: NOAA GFS every hour, at the surface and up to about 31 km, and the NOAA GEFS ensemble where this site holds it. JSON, gzip compressed. Weather data by Open-Meteo.com (CC BY 4.0) and NOAA. For 2026-09-22 12:00 local time at 47.7059, -122.1385.

The log recomputed for your own sea-level pressure and temperature. Columns: time, altitude as recorded and adjusted, raw altitude as recorded and adjusted, pressure.

This file is built here from the signed log, so it carries no signature of its own. Anyone verifying a claim should be sent to the flight page and build their own from the original.
