Yep. The GLV fuel and oxidizer pressure gauges
worked excellent except for the IPS . Stage two IPS
fuel gauge failed to the full max deflect:i.on posi
tion just shortly before POGO started, ancl stayed
in the OFF position until after staging. It came
back on and worked for about a minute and then went
back off again. The altimeter worked just like it
worked in the altitude chamber. Stopped at 96 800
feet .
It was very jerky on the wa:y up.
It was erratic going up .
And I don ' t guess you ca.n expect a pressm·e alti
meter like that to follow as fast as that booster is

Coming back on reentry, why, we were apparently a
