A plane crash in Florida has killed nine people, including a married couple and their two toddlers. The victims also included a 20-year-old co-pilot. Authorities are investigating the incident, which occurred in the early hours of the morning.

The crash involved a small private aircraft that went down near a rural area. Emergency services responded quickly but were unable to save the passengers. The identities of the victims are being released in the coming days.

This is the second major aviation incident in the state this year. Last month, a similar crash near Tampa resulted in four fatalities. Both crashes have raised questions about safety protocols and pilot training. Officials have not yet confirmed the cause of the crash, but preliminary reports suggest mechanical failure may be a factor.
