Hello I was loading my flight on Sunday it was around twelve thirty and I noticed an American 757 taking off as he was climbing I heard this funny noise and saw two orange fireballs shoot out the back of his #1 engine. I was wondering what could have caused it or is it something that happens reguarly?

What you saw was definately a compressor stall, maybe caused by bird ingestion or possibly a fan blade failed and was released against the engine case. Was it raining?...Intense precipitation can also block airflow through the inlet and cause a compressor stall.

After a compressor stall isn't that considered an engine failure? If not what does the a/c do on climb out. I mean with one engine gone that climb is going to be hellish. I'm surprised that the a/c didn't come back...

You may or may not know you had a compressor stall.If you happen to be looking at the EPR gauge you will see it but if its just a transient thing you may not.I'v also taken a bird thru an engine and the only way we knew was on the walk- around before the next leg.
