A teenager managed to pull himself clear from burning wreckage after a light aircraft crash killed his parents near Detroit.
Police said the single-engine plane was on its way to a small airfield just outside the city when it hit trees and crashed in wasteland.
A Federal Aviation Administration spokesperson told WXYZ Detroit that the pilot of the Cessna 210 had reported problems with its landing gear and fuel supply before the crash.
Video showed the aircraft burst into flames and some time later the 17-year-old is seen emerging from the wreckage.
He has been identified as Peyton Boaz.
His parents Greg, 54, and Julie Boaz, 48, from a suburb near Houston, Texas, were killed in the crash, the Houston Chronicle reported.
KTRK-TV Channel 13 reported that Peyton was taken to a hospital in Detroit in a critical condition after receiving third-degree burns.

There were reports that the aircraft had been en route from Arkansas.
Cordell Owens has been was credited by police for helping the teenager escape from the wreckage by using an axe to break a hole in the plane.
He told WXYZ Detroit: “The plane crashed and we start running towards it and it was a small plane and the flames were out of control.
“It started burning and the gentleman in the plane started hollering and screaming, and that was when I went to work.”
A bar founded by Mr Boaz posted a tribute to the couple on its Facebook page.
