Plane Parts?

This is one of the craziest things that I have ever witnessed/experienced.  The boys were both playing soccer up at the Broomfield Commons and one of the engines from a plane that had just taken off from Denver International Airport (DIA) about 20 miles away exploded.  The sound could be heard from quite far away and then it looked like confetti/pieces of paper were coming down.  Quite quickly the kids realized that it wasn't paper that was coming down but rather huge pieces of metal from the engine coming down.  They turned and ran for cover as pieces started impaling themselves in the turf fields and surrounding neighborhood.  Miraculously, nobody was injured though some larger pieces came down on some nearby houses.  As kids tend to do things without thinking, many pieces were seemingly grabbed for pictures.  We later had to explain that they couldn't keep the pieces and that the FAA would require those pieces to help determine what happened to cause this accident.  It is also worth noting that the plane did successfully return to the airport and land without any injuries, but I am sure that would have been quite a scary flight to be on!
