A family, including a toddler, died on Father's Day after a glider crashed in Fort Bend County.

Deputies said the crash happened in a field off Highway 36 and Cougar Road near Willis shortly before 5 p.m. Sunday.

Investigators said a glider plane with 63-year-old Fred Blair as the pilot, Matilda Blair, 32, and her 3-year-old son, Andrew, as passengers were in the light aircraft being towed by an airplane. When the glider was released, it took a nose dive and crashed in the field.

"It's actually pretty tragic to know a family, mother, son died on Father's Day," said Chalsky Michalsky, a resident who lives near the crash site.

Fort Bend County Sheriff's deputies were still working the scene Monday morning.

"We seen the gliders go back and forth all the time and we heard a really big boom and we came outside to see the smoke in the air and all the ambulances coming down," said Michalsky.

Officials said all the victims were related.

The Federal Aviation Administration and the National Transportation Safety Board are investigating.
