That's what experience buys you.
And practice. Watching this one and the STS-93 launch would put to rest any doubts about the value of sims.
This was fun. There weren't any issues, problems, etc with the entire count and the Range issue. We were all watching the clocks, watching our systems, listening to the loops, etc and then everything picked up with 2 seconds to spare.
It was a lot like the movies and someone having to disarm a bomb and clipped the right wire with only a second or two to spare.
It's great to be back to flying!
I was wondering something. I know that PLT has always historically had a bit of a time crunch to get the APUs going in time. In this situation, I was thinking he could have been caught a little flat-footed (understandably). But I didn't catch it real-time. Obviously he got the job done, but did he get it done normally or just barely in time?
The reason we took it to 5 minutes and held there is because that is where we start the APUs. We didn't want to start them, burn the fuel, etc if we were going to scrub. So the PLT started them just when he should have as one of the first things done when the count picked up at the T-5 minute mark (which was after the 2:58 seconds of drama)

Correct me if I am wrong, but the PLT only activates the APUs after the 5:00 mark (GLS GO for orbiter APU start). APU prestart is done at ~6:15. Assuming the APU prestart was complete on time, as the count resumed the GLS GO would have been given, OTC would have called for the PLT to perform APU start and the PLT would have had the normal amount of time to perform the task.
"APU Pre-start" is littlerally just opening up the isolation valve. It sounds more dramatic than it actually is.

I think that's right, but normally he'd have been expecting 4:59 to come right after 5:00. This time, we didn't really know 4:59 was going to come until about 3 seconds before it did! So I was thinking he might have gotten a late start.
Fair enough... but had it been me, my finger would have been waiting on the next switch, ready for that call. So I can only imagine PLT Boe would have been all over it like the proverbial fat kid on a ham sandwich.
Everyone is listening to the launch team on OIS 212 and they knew it was coming. (And all those words on 'being ready to pickup' apply to the crew, too, so they were just as ready to pickup.)

Well, it sure was exciting for me watching it on my computer. I couldn't have been the only one yelling at the screen: "COME ON! COME ON!"  Great coolness and professionalism among the launch personnel. "Steely-eyed missile men (and women)" indeed.

You weren't. I swore something surrounding "Come on!" when the SSMEs fired up, whilst shaking my fist  There's only York City scoring and Shuttles that make me do that!

I had a 'Dr. Appointment' today, so I could at least watch the final launch of Discovery in HD!!
Well worth it, even though I was getting a bit nervous during the RSO issues...lol

Very nerve-wracking moments indeed. But rather fitting for Discovery. Her maiden voyage was delayed during the count for several minutes; her last launch was delayed a few minutes during the count. Her first mission was rolled back to the VAB; her last mission was rolled back to the VAB. Thank the gods she didn't repeat that post-SSME start RSLS abort from STS-41D.

I take it the ET handheld footage wasn't worth showing? Schedule shows it should have been shown 20 minutes ago.

From earlier sounds like the lighting conditions were not good enough

One hour until the crew go to sleep. Crew wakes up at 5:50am Central. TPS survey begins just after 10am Central. For new people here, we have specific threads for the flight days and cover every event within the FD. Expect to see a lot of images of RCC panels tomorrow  Will probably set up the FD2 thread now as a placeholder to allow for timelines and NTV schedules to be posted for the interim.
