Mid-flight 747 blown engine
Hello all,
Now mid flight ICN - DTW Delta One on a 747 upper deck. Heard a loud bang an hour ago and was told 15 minutes ago we lost an engine. Making an emergency landing in Tokyo which is still a 4 hour flight back as we were almost to Alaska.
Question 1. Am I safe? It's my understanding the 747 has 4 engines?
Question 2. .... question 2, I just want to land safely.

Good grief, these 747's are falling apart. How many incidents has Delta had in just a few months time?
To answer your question, yes, the 747 can fly just fine with three engines as long as it wasn't an uncontained failure. If you were almost to Alaska I wonder why they would turn back to NRT?

Take a deep breath and relax. While this is no doubt disconcerting, the 747 can fly just fine without one engine.
Hopefully you won't be delayed too long at NRT.

According to Flight Aware DL158 was just north of the Japanese island chain when they diverted. Going to NRT kept them overland for most of the route vs. an over water continuation.
ETOPS may require that they take the shortest over water route on the diversion.
Also, parts and maintenance will be easier to deal with at NRT which is a regular Delta 747 destination than ANC which is not.
The flight landed at NRT at 6:01PM JST.

Are they ever more than 3 hours from an airport on this route? If not, then it appears ETOPS does not apply to a 4-engined aircraft on this route.

I assume since the flight flew all the way back to NRT it was not a true life or death situation. In those cases they will land anywhere and figure our the logistics from there.
NRT probably had a spare crew as well. Where ANC most certainly doesn't. Plus depending on the time there may not have been any customs staffed at ANC. (quick google search says customs goes home at 4:30)
So while increasing flight time, going back to NRT probably greatly reduced your delay....Glad everyone is safe and that you didn't end up in Goose Bay for a day and a half!

4 hours back to NRT vs. 6 hours to ANC seems an easy call before one even gets to over water time, relief crew, spare parts, and relief aircraft.
DL won't sacrifice safety, but once safety is in place, it does a good job of looking at overall logistics to minimize delay at scheduled destination.

Ages ago I was on a DC-10 that blew an engine over the Atlantic. We diverted to the nearest appropriate airport, which was Shannon. If the captain hadn't announced what was happening, I would have been unaware of anything different in the way the plane was flying. The landing was similarly uneventful. Relax; you're in good hands.
