If I was the editor who made any of the changes unless it s a no brainer I usually post an explanation on the Talk Page or put a discription in the summary of the edit Some editors feel the article is too long A few weeks I tried expanding out a section on a quote by an engineer but it was eventually removed Every edit on this article is heavily scrutinized There s no point in trying to make any major changes to the article unless you re prepared for the inevitable battle that will ensue
