The daughter of two-time Super Bowl champion Bruce Collie, Devyn Reily, was tragically killed during an airshow this weekend ... when the plane she was flying crashed into Lake Winnebago in Wisconsin.
According to authorities, Reilly's World War II-era T-6 Texan plummeted into the body of water at around 9 a.m. on Sunday ... while it was participating in the AirVenture Oshkosh 2023 event.
It's unclear what caused the accident ... though one witness told NBC 26 the aircraft began "spinning" before it splashed down in the lake.
