Checking effect of HIMIL body to Dump connection: 22:52:00 @ 41 kft on SA, opened HIMIL-Dump valve 22:54:05 closed 23:12:48 @ 15 kft opened 23:14:48 closed lost satcom at 48.8 S @ 6 kft Program hung over midnight. No cals were pending, next cal was going to be just a LS-HS. Suspect something in high rate sampling routines to do with a reference time check. Unfortunately, missed entire BL of third dip (but got a MED flask) - next one should be interesting. 00:28:20 set calint to 0 to force a cal as approaching the the top. . . hopefully finish before too much descent . . . but has to purge/HS/LS for 9 min. . . started down at 00:34:00 and still on LS, so will miss first 5 kft of descent. Looks like cals can be sped up by closing AEROS. 01:15 Last two profiles showed interesting O2 layers at different altitudes. 01:34 To Manual Control to sample at 500 ft 02:43 Flask number 20 valve broke off during close SIDE SLIP TESTS 04:12:47 - 04:17 = 2 cycles, but with lots of O3 variability 04:20-04:22 = 1 cycle with constant O3 No apparent O2 or CO2 effects 04:29:20 to LP (checking for alt dep effect) 04:34:15 switched back to sample and Stopped program to do P tests Measured HIMIL body and cigar P, body CO2, and effect of HIMIL-Dump connection until 05:03 05:03 restarted as 110830c
