GP, subject incident came up recently in conversation and although I was in SNN at the time, memory dulls after so long .... I'm almost certain it was 06 and crash site was in/around Aerospace's Hangar (built since) ..... not sure why water was mentioned although if you walk around any Shannon field in November your likely to end upto your neck in the stuff at some stage ..... I remember visibility was desperate at the time ..... PAS's were DEC computer guys going back to HQ after a trip up to DEC Galway ....
I have not been able to find any more info than that in the NTSB link kindly provided by C ......
