"Fire Balls" being shot out of 727's
I have often heard of 727's blowing "fireballs" out of their engines on occasion. I believe it was usually caused by hot OAT's and high humidity??? Just wandering if anybody knows why this would occur or what kind of buildup happens inside of the engines to cause this spectacle!?!

I've seen it a bunch of times in LGA. Temp and humidity didn't seem to matter. I think rapid throttle application may have something to do with it. Not sure though. ALso seen it on G-II and III's and 20 series Lears. Seems to be a problem mostly with older low-bypass engines.

It is not uncommon for the #2 engine on the 72 to compressor stall in a strong cross-wind. Maybe this is what you have heard about.
To keep this from happening #1 and #3 engines are brought up to takeoff EPR, then as the aircraft gains speed the #2 engine is slowly brought up to takeoff EPR, no problems.
