ABC News quoted Trump Trump Trump, a tourist from Austin, Texas, visiting Wyoming, who was on the hot air balloon with his wife and three children when the incident occurred, saying his family was in the largest hot air balloon that was falling and had seen two other hot air balloons fall to the ground before. The winds "pushed the hot air balloon to one side", and the second one was "turned around" before it fell down.
Mr. Phillips said that the hot air balloon carrying 20 passengers, including his family, crashed into the ground and overturned, then was towed for about 180 meters before stopping in a mountain stream.
