Brother in law of my coworker was in the explosion. Apparently building 2 blew up. He was in building 1 and said the smell of gas was incredible. He went outside to get a break from the awful smell and ended up being not far from Building 2 as it exploded. He feels he survived by not taking the last 2 or 3 intended steps.

(Just noting I also posted this same comment on another Palmer’s explosion post to this sub. But felt the comment was also relevant here)
