sharp nosedive(Maria Klavdieva; nosedive is a "sharp drop in altitude" by definition Val_Ships; in addition to the meaning you are referring to, this expression is often used metaphorically, e.g. "BBC NEWS | Business | US economy suffers sharp nosedive". VAl_Ships, just try to google it - you will be surprised! Maria Klavdieva; let me try it again: "sharp" is redundant when combined with "nosedive" - the key word means a "sharp" action by itself Val_Ships)
