Dangerous Dive is a term used to describe a type of aerial maneuver in which an aircraft performs a steep dive and then pulls up sharply at the bottom. It is considered to be a dangerous maneuver due to the high speeds and g-forces involved, and is usually only performed by experienced pilots. The term 'TAILSPIN' is an 8 letter word that is often used to describe this maneuver, as it involves the aircraft spinning around its vertical axis as it descends.
