The GE90 jet engine is not the only jet engine that forms a mini tornado when at full power, but it is one of the few that is known to create such a phenomenon. This effect is caused by the high-velocity air coming out of the engine's exhaust nozzle, which can create a low-pressure area behind the engine. This low-pressure area can cause air to rush in from the sides, creating a swirling vortex of air and often causing debris to be suck e d in. Other jet engines may also create similar vortexes, but they may not be as visible or pronounced as the one created by the GE90.
