There were callouts on the Technical Webcast for AFTS, is that what I think it is?
That would be the autonomous FTS. First time they are using it.
Quote from: Herb Schaltegger on 02/18/2017 02:14 pmI didn't hear it on today's loop (maybe I missed it), but isn't there a general announcement they make sometime around T-20 minutes or so that no holds will be called after T-30 seconds or something like that? (Meaning that aborts after that are called by the vehicle health management system itself, right?) If so, did someone override that rule and call an abort late or did the vehicle do it?I'm pretty sure it is the 10 sec mark that is the last manual opportunity to abort (usually by the launch director). We have seen an abort at T-0 which was done by the computer. It was pretty clear at t-1.30 when the launch director didn't confirm go for launch that they were taking a look at something.

Musk also tweets:"System was green for launch. I called it off."https://twitter.com/elonmusk/status/832995083519614976
If anything Musk is showing his employees that it's OK to err on the side of caution, which is part of corrective actions they put in place after the CRS-7 flight failure.As for NASA, they learned the hard way about the consequences of giving in to schedule pressures, or ignoring an abundance of close calls. So I would hope that NASA is heartened to see how much care SpaceX is putting into safely launching their cargo on this mission, since that helps them to understand what the thinking will be when humans are the cargo.

This visible event does not mean it is an engrained culture. There is public perception here. If it were a Boca Chica or VAFB launch with a comsat, the decision might have been different.Also, NASA is not monolithic. The group that monitors these types of missions is different than the shuttle people.

And why did he wait? Why wasn't the scrub called earlier? What could have changed after the issue was detected to make it ok to launch and then not ok.
The launch decision process should work without Musk's direct involvement.
Also, NASA is not monolithic. The group that monitors these types of missions is different than the shuttle people.

The group that monitors these types of missions is different than the shuttle people. Maybe. But in the video from the Orbcomm landing, a few seconds before launch he asks something like "Is there anything at all here that doesn't look right?" The answer then was No, but it would not surprise me if he asked that on many other missions as well.
Well you have to get used to the fact that in the private sector there actually are cases where there is one person who can override all other decisions and scrub a launch
Stop with the Challenger references (and any for Columbia for that matter). Decades ago. Like I said, different part of NASA that works these and other non shuttle launches.
So, why are you same rah rah people not calling out Spacex for submerging carbon fibers in LOX?
The point is about processes
Sometimes blindly following a process is the wrong thing to do. Bravo Space X for not being afraid to pause and look some more. As someone else said Musk is setting a standard for the rest of the team to not be afraid to say no and that's good. Last thing any of us want is another launch failure.
