Narrative:

On climb out at 22800 ft, loud noise that shook airplane was heard and felt. #2 engine egt rose to 600 degrees, #2 EPR dropped to 1.25. After throttles reduced, all indications returned to normal. Returned to bwi, landing uneventful. Post-flight inspection: most compressor blades damaged, engine required changing.
