ATC Watcher, for what it is worth, 211 was on frequency for 12 minutes from 08hrs:21 mins:45secs to 08:33:34 of which 06 mins was on approach up to first attempt to land and 06 mins thereafter up to 211's last transmission. At approx 08:27:20 Tower says you are going to runway 20 which would fit in with your information that ATC had visual with the aircraft. Around 06 mins later the aircraft crashed.
