(Ft. Lauderdale, FL) — It was just a misunderstanding, is what officials say about a bomb threat that caused a flight from Florida to Minneapolis-St. Paul International Airport to turn around last night. Spirit Flight 596 was carrying 92 people when it was believed one of the passengers mentioned a bomb. Officials searched the plane once it returned to Florida and no immediate threat was detected. The Broward Sheriff’s Office says after interviewing suspects, witnesses and the flight crew, agents determined there was no actual threat.
