Andrew Allison was 17 when he disappeared from Orange Park, Florida, after an event on February 6, 1989. Investigators believe he stole a 1976 Piper Warrior from the flight school where his father worked as an instructor and took off from Herlong Airport. Neither Andrew nor the aircraft were ever found despite searches, and no explanation for why he took the plane has been established.

The case remains unsolved with no trace of Andrew or the airplane discovered to date. If anyone saw a small single-engine plane leaving Herlong Airport that day or has memories of Andrew’s activities or state of mind in the days before February 6, any information could be important.
