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
