It's an older one that happened here in LSZH. SWR 101 was on normal days a B747 inbound to Zurich from JFK. ACC called the APP controller and told them that SWR 101 was coming in with only 3 engines today (in fact it was an MD-11 on this day!) The Approach Controller immediately notified the fire brigade, everything was prepared for a one engine out landing with a 747. The pilots didn't get it as the APP ATCo told them that the fire brigade was ready, and the fire brigade was pretty upset, when they saw an MD-11 on final approach
