An Avianca airplane traveling from Medellín, Colombia to JFK in New York City had to make an emergency landing in Miami after encountering extreme turbulence.   During this turbulence, the airplane dropped 25,000 feet in just a few minutes.   Eight passengers were hurt by the turbulence's impact.   According to some passengers, the turbulence took them by surprise... some of them were walking around the aisle or even in the bathroom when it happened.   #nyc #miami #plane #jfk
