Agree with Sid's points in the posts above.
In this sad case, there was no building or cliff ahead. They very nearly made it successfully onto the ground. We don't know yet if the RadAlt is a factor in the outcome, but I would suggest that if this crew did have and use the RadAlt information, it was that which allowed one of the crew to survive. If they didn't have it, they might all have survived had they had the information.
Sincere condolences to the families and best of luck to the surviving crew member for his/her recovery.
