Two single-engine float planes collided as they flew near an Alaskan lake and one of them crashed and burned, killing the four people aboard, authorities said. The second plane landed safely despite significant damage. One plane, a Cessna 180, was destroyed by the impact and fire, Federal Aviation Administration spokesman Ian Gregor told The Associated Press. "It was engulfed in flames on the ground," Alaska State Trooper spokeswoman Megan Peters said. The crash around Amber Lake near Trapper Creek, 80 miles (130 kilometers) north of Anchorage, came nearly three weeks after another in-flight collision that remarkably left the 13 people aboard the two aircraft unhurt. The second plane in Saturday's crash, a Cessna 206, sustained significant damage but was able to return to Anchorage International Airport and make an emergency landing, after the collision.
