Previous engine stall on 1549?
I was flipping through the channels when I saw Bill O'Reilly talking about a previous stall of the engine(s) on Flt 1549 two days prior to the Hudson Miracle. Now, considering the source, I did some internet searching and found two articles, one of which is linked below. Is there anything to this? It seems one thought is that this could have weakened the engines making it more susceptible to stalling during a bird strike. I was just curious why I had never seen anything on here about this!

It was discussed in the thread on the accident, but you can be forgiven for missing it since it was 59 pages into the thread before those reports surfaced.

I should have added that the NTSB is investigating - maintenance was performed on the engine in question after the earlier compressor stall but I don't know if they've interviewed the pilot involved yet. I'd almost guarantee that it'll be something they'll be looking at when the engines are taken apart at the manufacturer.

A compressor stall is not the same thing as an "engine stall" in a car. It is a momentary disruption in airflow through the compressor section of the engine due to an incompatibility between the rotational speed of the fan and the speed at which the air in entering the engine. It can be caused by factors either internal or external to the engine.
Jet engines do not continue to run after ingesting a goose. Doesn't matter what condition they were in before the goose ingestion.

It is possible for a jet engine to continue to run after ingesting a goose. Particularly if it only hits the bypass section (the outer part of the large fan that you see at the front of the engine) rather than entering the engine core. If a bird as large as a goose enters the core, however, it likely is toast.

I've seen video of a man sucked into a jet engine and survived. Talking about luck!

Sure, anything is possible, but when an adult goose goes through the fan section it's going to cause a lot of damage. I wouldn't expect it to continue producing any significant amount of power even if the bird misses the core.

What generally causes a compressor stall?
I have only heard of one occurrence and it was an article in Flyling Magazine that I read. They reported that a flight crew was ferrying a CRJ with no passengers onboard and they decided to play rocket man and see how fast they could climb to FL40. Unfortunately they were unable to recover and crashed killing both the pilot and FO.
How common are compressor stalls and what generally causes them?
