HISTORY OF FLIGHT
On April 20, 2006, about 2345 eastern daylight time, a Cessna U206G, N120HS, piloted by an instrument rated private pilot, was destroyed on impact with trees and terrain while on approach to runway 35 at the Monroe County Airport (BMG), near Bloomington, Indiana. The personal flight was operating under the provisions of 14 Code of Federal Regulations Part 91. Night instrument meteorological conditions prevailed at the time of the accident. An instrument flight rules (IFR) flight plan was on file and was activated. The pilot and four passengers sustained fatal injuries. The flight originated from the Purdue University Airport (LAF), near Lafayette, Indiana, about 2245.
The person representing N120HS contacted the Terre Haute, Indiana, federal contract facility automated flight service station (AFSS) to get a weather briefing about 2213. The AFSS briefer at position "PF-3" gave the following brief, in part, to the pilot:

The transcript of the weather briefing showed that the pilot did not give an alternate airport to the briefer when the flight plan was filed. The briefer did not ask for an alternate airport and was not required to ask for one.
About 2319, the pilot checked on with the Air Route Traffic Control Center controller working the Shelbyville, Indiana, sector (SHB R). The transcript of their transmissions, in part, stated:
