Because different people grieve in different ways, and I suspect a non-zero number of "us" will want to know more about the incident, I offer the following two resources, not for macabre voyeurism, but for those who want to perhaps understand more of the technical details. I know that these sites have been helpful to me in the (fortunately very few) times in the past when I've lost pilot friends of mine.
The FAA site will likely have the basic data posted tomorrow: http://www.faa.gov/data_research/accident_incident/prelimina...
The NTSB will have a preliminary report in a few days, and a final report will be months in coming: http://www.ntsb.gov/ntsb/AccList.asp?month=10&year=2010
If those resources are helpful to just one person close to Luke and family, it was worth the 5 minutes it took to post this.
