<font face="Verdana, Arial, Helvetica, sans-serif" size="2"> 7:30pm flight did not leave until close to 9:00pm, as 827 form Honolulu was five hours late in arriving. I assume that they had to DH a 744 from SFO to cover for the one stuck in NRT.</font>
This brings up an interesting point - what to do about getting the broken engine fixed? I had a discussion with a captain about this issue once. In my case, it was a CO 777 that lost an engine upon departure from NRT and had to return. The damage to the engine was extensive enough that it couldn't be fixed locally.
Apparently, on most aircraft, what's done in this situation is that the airline flies a spare engine as cargo from their maintenance base to wherever the stuck plane is, swaps the engine out, puts the aircraft back in service, then transports the broken engine as cargo back to their maintenance base or wherever they have engine repairs done.
The problem with the 777 engine is that it's too big to fit as cargo into any regular commercial airliner. CO had to charter one of those Antonov "spruce goose" models to fly the spare engine to NRT and take the broken one back home, which greatly increased the cost of the incident.
