A man and his three children in a Cessna 170B and the pilot of a Cessna 172 were killed in the wreck just after noon, according to National Transportation Safety Board investigator Clint Johnson. Both were single-engine fixed wing aircraft manufactured in 1955, state troopers said.
The planes were flying at altitudes between 500 and 800 feet when they collided above the Palmer Hay Flats in a remote area about 10 miles south of Wasilla.
"It appears that the westbound aircraft apparently saw the other aircraft at the last moment, tried to avoid the collision, but unfortunately that didn't work," said Johnson, who did not identify which plane that was.
