The National Transportation Safety Board is investigating a weekend crash in Florida that killed a family from Georgia.

A woman, a man and two children between the ages of 6 and 8 died in the incident, which occurred Saturday at the Williston, Fla., Municipal Airport, officials said.

As many as 20 airplanes flew out of the airport later that day, but authorities did not learn about the deadly crash until the next day, said Clay Connolly, Williston’s deputy chief of police.

The plane, a 1948 Cessna 170, was registered in Texas to Nathan Enders, “an air traffic controller in Georgia who worked at the FAA Terminal Radar Approach Control in Peachtree City,” Federal Aviation Administration spokeswoman Kathleen Bergen said.

It was not immediately clear if Enders was one of the victims. The names of the dead and their relation to one another have not been released.

Authorities do not know what caused the pilot to crash, and a preliminary report isn’t expected for weeks.

What officials do know is that the plane refueled somewhere in Georgia at 11:30 a.m. and arrived at Williston airport about three hours later, Connolly said. Williston is about 105 miles northwest of Orlando.

The plane tried to take off at 3:10 p.m. but crashed just beyond the end of the north side of the taxiway, Connolly said.

The plane was equipped with an emergency locator transmitter, which continued to send radio signals that should have been noticed by pilots within 2 or 3 miles, he told The Gainesville Sun in Florida.
