I was on an SAS flight from Copenhagen back to the US. About 3 hours out of Copenhagen we were over icebergs only and they announced one of the engines was not working and that we would dump out fuel at sea and turn around and try to get back to Copenhagen.

I did not panic or worry, as it wouldn't have made things any better. Until you have been in a situation like this, you don't really know how you would behave/react.

We did get back to Copenhagen and they immediately tried to convince everyone to get back on another plane which would reach Chicago at 2 am, then they would try to rebook those of us going to the West Coast. Virtually everyone went, but as I am disabled and doubted they would take good care of me getting me to/from ORD to a hotel until a flight to the West Coast took off much later the next morning, I refused
that option and insisted to be put up in a hotel after the ordeal. They originally refused, but finally relented, and I took the same flight the following day, uneventfully.
