A gravity turn is commonly used with rocket powered vehicles that launch vertically, like the Space Shuttle. The rocket begins by flying straight up, gaining both vertical speed and altitude. During this portion of the launch, gravity acts directly against the thrust of the rocket, lowering its vertical acceleration.
Most rockets need to be supported and held down for a few seconds after ignition while the engines build up to full thrust. The vehicle is commonly held on the pad by hold-down arms or explosive bolts, which are triggered when the vehicle is stable and ready to fly, at which point all umbilical connections with the pad are released.

The more than 400-foot rocket, powered by 33 Raptor engines, appeared to lift off successfully at 4:37 p.m. CT from SpaceX's launchpad at its Starbase facility near Brownsville, Texas.
A rocket is destroyed during flight to prevent it from leaving the launch corridor or continue an otherwise errant flight. The resulting destruction is required to scatter rocket parts over a small area, ensuring the majority of the parts stay within the launch corridor and are able to cause as little damage or injuries as possible.
A Chinese rocket broke apart in low-Earth orbit after delivering 18 satellites to space. Experts are still assessing the risks of the event.
