Also - the scrub was caused by Ground Support Equipment not configuring correctly. Nothing wrong with Starliner or the rocket (this time)
I read a puzzling story about this on a news site this morning. It said that the three computers that conduct the final launch sequence are setup to "boot up" at T-4:00 and the launch was aborted when one of the three had not completed booting by T-3:50.
This doesn't make sense to me. Why wait until T-4:00 to boot these computers? Why not have them up and running well in advance?
I suspect this is just idiosyncratic reporting that I read and the event that actually happens at T-4:00 isn't a "boot up" but a switch over or something like that.
Anyone have more info on this?
