Feather Cloud

I saw this while riding to my parents' house in Westford yesterday around 12:45pm.  I think it is perhaps a fallstreak cloud without the fallstreak hole.  Some people are saying its a "chemtrail" and others are saying it is an angel feather.  While I prefer the scientific explanation for clouds, I did hear that a young boy passed away around noon yesterday and many are taking comfort in this cloud.
