About 3-5 min before the launch time there were many voices chiming in to say "ready". I remember one of them, "OSM" had to be asked twice before they responded ready, which was different than all the rest. Anybody on here know what "OSM" stands for? Is it orbital station module? Anyways, I was just wondering if it might have been connected with the abort (such as they saw the high pressure build up in engine 5).
