A Concorde pilot I used to know, showed me a photo of an engine that had eaten part of an intake door mid Atlantic. It was a bit of a mess.
IIRC one engine surged, part of an intake door broke off, came out of the front and was ingested by the adjacent engine. The aircraft landed at Shannon with one engine shut down and one on reduced power to stop it surging.
I think this would be about 1997.
