I have heard of the famous cottage cheese,was it in a 747 by any chance?The guys were almost sick when they smelt the cottage cheese.I can imagine that the smell of these masts must be absolutly awful.Amazing,there is a snake small enough to fit in the tiny holes of a drain mast.Do you get blocked masts mainly on bigger jets like the 747 or 777 or do the smaller ones like the Embraer E-Jets also suffer this?Sorry about all the questions but I find it all very interesting.Which jets out of Airbus,Boeing,Embraer,get the most problems with blocked masts?Worst story I've heard,a guy was working on a mast and someone up in the lav had a pee in the sink,
