Mike, etal

Your metars/overcast got me thinking of an “approach” view of the situation.  So I plotted the lat/lon’s on the DNN ILS approach plate.   Interestingly according to the plate and sectional, there aren’t any “mountains” to speak of between any of the radar points and the airport.  He went right through the localizer at the glide slope intercept (high at that point) and they appears to have swung out way too wide.  It will be interesting to see more data, ATC communication, etc.

Colyn,

 

Interesting.

 

I'm not sure how accurate the flight aware numbers are but I did some checking.  I'm sure the altitude numbers are pressure altitude from the transponder, airspeeds are ground speeds.  I pulled up Google Earth and entered some of the lat lon numbers from your post to get a feel for where he was.  I converted the decimal lat lon to degrees and minutes.

 

I plotted:

 

The Dalton airport

The 12:24 fix at 16,400 MSL (15,700 AGL)

The 12:26 fix at 11,700 MSL (11,000 AGL)

The 12:28 fix at 7,700 MSL (7,000 AGL)

The last fix, presumably the crash site

 

The last fix is close to a divided highway with a grass median.

 

The 15,700 AGL entry is only 5 1/2 miles from the airport.  The 7,000 AGL entry is 8 miles from the airport.

 

See attached Google Earth image.
