Starts take-off roll or perhaps only spools up. Gets a warning of some sort. Vacates runway. Problem quickly rectified. Returns to H/P, awaits for an inbound to land and vacate, and departs. Probably happens a couple of dozen times a day around the world. Nothing dramatic! Nothing sensational! I do think that some posters over do it now with these "what happened" postings and I can understand why some may feel compelled to making vitrolic or sarcastic replies.
