Jaba,
I'd like to see how you flare an aircraft in no vis with no radar altimeter, an altimeter that can be out by 75ft on a QNH that can give you at least another 30ft variable. ILS is called a precision approach for a reason - you need precise control of your aircraft to fly one. In this sad occasion and from all reports the poor pilot did not have a controllable aircraft in the sense that would be required to fly an ILS. And last time I checked richmond was suburbia.
Any pilots goal in this situation would be no casulaties - I doubt your solution would provide that.
I havn't instructed in a while now but I am sure they still teach you how to glide into a field and not how to flare off an ILS in fog on 1 or no engines.
