HRABOVE, Ukraine (AP) — A child’s jump rope, its yellow handles blistered and charred. A burned book in Tagalog. Chunks of twisted fuselage. More than seven weeks after being shot from the sky, the wreckage from Malaysia Airlines Flight 17 still lay strewn Tuesday across the fields of eastern Ukraine.

As evidence of the July 17 aviation disaster that killed all 298 people on board remained exposed to the elements, investigators hundreds of miles away in the Netherlands — who have not yet visited the crash site because it is deemed too dangerous — released a preliminary report that left key questions unanswered.
