My wife is presently on Flight 1853 on Sun, 29 May 2011 - which just landed in ATL and there is smoke in the cabin. Passengers are still onboard, emergency exits have been opened. While on the phone with my wife, I heard someone on the overhead PA announce that they think that there was a contaminant in the air system.

i'll post a follow-up when she calls back.

Surely there should be some sort of compensation?
