118:15 QCLS shut down on ascent out of AK 18:42:30-18:43:30 AO2 Inlet Breath Test #1(not really) Turns out AO2 was in cal. 18:42:30-18:43:30 AO2 Inlet Breath Test #1 Response to breath test possible, but seems to be mirrored in MEDUSA. Trying again in a few mins. CO2 signal too messy at top. Had to forego second attempt. Sampling only flasks 7-32. Flasks 1-6 were sampled on RF04, the first attempt at the polar flight. 22.15~ accidentally closed wrong flask briefly (pos 23) for about 5 secs.
