“we heard. V loud.”

Another sends via email:

“Here’s a photo of some people on the street responding after the recent ‘boom’ heard on 3&L. I was on 4&L when it happened, definitely felt a small shockwave. We walked back up so our friends could check on their house, but then turned away so were weren’t walking towards the blast. All the students in that dorm were on their balconies and people were all coming out of their houses to investigate.”
