What were all those brief 'puffs' from the vehicle at random directions during the end of first stage?
Normal puffs due to slight variations in main engine combustion. Pretty usual for RP-1 engines.

Thanks, I was hoping somebody with more eyeball time on previous launches would be able to recognize what's 'normal'.

S3 spinup and separation. Last time that will happen on a Delta II.

LOS

There has been an unexpected loss of signal. It is believed to be a problem with the ground station.

LOS - "will update when we get additional information."

Vehicle is apparently ok, it's a tracking station in Guam.

Hopefully it is a ground station problem and not...
Best quote heard during an inspection, "I was unaware that I was the only one who was aware."

I think we're past S/C Sep time, but they have no telementry.
