JACKSONVILLE, Fla. -- More information is surfacing about a deadly plane crash on Jacksonville's Southside.
Authorities said Dr. Michael Huber of Port St. Lucie, Florida and his two daughters, Tess, 20, and Abigail, 17, died Sunday evening.
The small plane they were in crashed in a pond behind Nettington Court in the Sutton Lakes subdivision off Atlantic Boulevard.
According to the flight tracking website FlightAware, the family left St. Lucie County at 5:20 p.m. Sunday.
Their plane headed north, ascending to its highest point at 5,000 feet, according to the site.
The site also reported that the family began descending toward the main runway at Craig Airport in Jacksonville at 6:09 p.m.
But as the Jacksonville Sheriff's Office has said, Dr. Huber reported to the control tower he was having trouble seeing the runway.
Authorities have stated that heavy fog could have been the blame for the visibility issue.
In a situation like that, aviation experts told First Coast News that a pilot should follow what's called a missed approach.
It's essentially a back-up plan for landing a plane that is included in the flight plan pilots file ahead of time.
The published missed approach for the Hubers' flight calls for the pilot to ascend to 1,900 feet while curving to the east.
But according to FlightAware, the Hubers' plane curved to the west and only reached a maximum height of 300 feet before crashing.
The website also reported that the plane was only flying at 84 miles per hour.
Marshall Wood is a Jacksonville-based aviation expert who offered this insight into why the published flight plan wasn't followed entirely.
"There are times when you don't follow the publish missed approach, and that's if you've been given some other instruction by the radar facility," he said.
Another reason, he told First Coast News, could be engine trouble.
It won't be until the federal investigation into the crash is done that we will know why Dr. Huber deviated from his flight plan.
The National Transportation Safety Board has begun their investigation that will almost certainly include audio recordings between the plane and air traffic control.
