C52, . what was said was radar contact was lost from the radar display which the controller was looking at when controlling the aircraft.
Many possible reasons for that : you can put any filter on your display being altitude or garbling filters at low level., but that said a normal APP SSR radar , can detect transponder replies quite low over the sea . A primary radar is more likely to have a filter a low altitude to avoid picking up windmills and ships..
I do not think the aircraft "disappeared" from all radars around, and they are quite a few.
It could indeed have picked up ice, stalled and dived down quickly,
The other possibility besides icing is that it could have had a major failure , i.e electric which would explain the sudden stoppage of the transponder and absence of mayday call.
