HUGGINS, Mo. (AP) — Authorities say a Utah State Board of Education member, his wife and two of their children died when their small plane crashed while taking off from a relative’s grass airstrip in southwest Missouri.

Missouri State Highway Patrol spokesman Jeff Kinder says witnesses reported that the Beechcraft A-36 got about 100 feet off the ground Friday morning before stalling. C. Mark Openshaw and his family were returning to their Provo, Utah, home after visiting relatives.

Kinder identified the other victims as Openshaw’s 43-year-old wife, Amy; their 15-year-old son, Tanner; and 12-year-old daughter, Ellie. The couple’s 5-year-old son was taken to a Springfield-area hospital in serious condition.

Federal Aviation Administration and the National Transportation Safety Board officials say the agencies are investigating.
