I was airborne in the same stream when the C130 was lost off Pisa.
It was still dark and flying at 500ft over the sea we unexpectedly encountered two to three eighths of stratus. Before we considered abort, and after only a couple of seconds the cloud cleared.
It is believed the C130 crew just pushed and flew straight in.
As far as I remember though, they were never blamed? No ADR / CVR so who knows what really happened?
