A popular aviation YouTuber and her father were killed when their plane crashed in Tennessee Thursday — just one month after she posted a video of her facing an “aircraft malfunction” at 4,000 feet.

Jenny Blalock, 45, and her father James, 78, went down around 11 a.m. and crashed on a remote road in Pulaski, a city on the central-southern border of Alabama, according to federal and county officials.
