I was on a CO DC10-30 going out of HNL when the blew the compressor in the tail engine. Scared the crxp out of me and about 150 other folks..but as below, not too serious a problem...
Toby: I'll take the optimist side.lol but Will's comment here below is probably closer to correct, especially on the newer versions. At any rate, there weren't near enough people. That is probably just a standard reposition move for them to feed their hub at KLAS.
80% likely a compressor stall. Not common but can be scary as hell sounding. Not a real danger though. Just like when your old Dodge truck backfires when it's cold.
I guess I must be like Richard here and well on the low side of that average. I flew for about 35 and can only remember 2-3 and I don't think any of them were due to an engine problem.
