No one was injured in a truck fire that erupted Thursday on Unalaska's Airport Beach Road. The incident occurred on the straightaway below Bunker Hill just after 11:30 a.m. Resident Nathaniel Buesing witnessed the blaze. "I heard the police siren going off," he said. "I looked out my window and saw a truck on fire, so I decided to video it." That video shows the hood and cab of a white pickup engulfed in flames while a big cloud of black smoke billows into the air. It also captures the arrival of emergency responders — and what sounds like the pop of a small explosion.
