BUR used to be ground handled by mainline, then it went to a regional, but they were still to expensive so then it became some third world ground handling company. I wouldn't doubt if the bus was parked short because in the video it looks like the 175 is on the yellow line. No excuse, just understanding how it happened, wouldn't want to be the 175 Capt. There really is NO room in that corner, it was crowded with two CRJ's in there.
