remember in milan linate (italy) some time ago: ground radar was off too-but there the accident happened...DC9 with plenty of passengers...
Interesting to see what comes out ie why was ground radar off or was it only the warning system? what will be implemented to avoid this? comparison possible with what happened at BOS? different freq or same used by controllers etc?
So far in this forum too little details to make judgments.
"ground radar was off due to downpour"???
sounds like some remote airports in africa-ILS U/S due to rain...
