We'll have to wait until the NTSB Report comes out. It was a CAVU day with light winds: "WEATHER: KDLN 151753Z AUTO VRB03KT 10SM CLR 26/07 A2990"
There is this news report from
http://www.kxlf.com/news/faa-2-people-killed-in-rocker-plane-crash/ "When the plane crash was reported this morning a police scanner report indicated that a plane was spiraling out of control with flames showing." and then there is this quote "The wreckage is fairly intact. There's a lot of impact related damage. We have all major structural components of the airplane present at the accident site. We do not have any evidence of fire. We have the left wing, the right wing, the tail section, the engine, the instruments, the cockpit controls," from a later news report

http://en.wikipedia.org/wiki/Piper_PA-38_TomahawkI'm so sickened to hear of this accident; my deepest sympathies go out to the families. I've never been so accepted into a community as I was in Butte Montana and I'm sure this loss is felt by many in that tight-knit community. The loss of Justin and Dick will be felt for a very long time.
