YouTuber 'Christine Diamond' uploaded video of 'crazy sounds' she heard in the skies of Delaware County, Pennsylvania on December 2, 2018.
'Christine' notes:
People around here keep insisting it was a firework show in the next town. However the sound was very loud and deep it did not sound like a firework show.
Two commenters on the video reported they heard the same sounds. One was in New Jersey and the other in Verona, Pittsburgh who said they heard the noise twice in the last two weeks.

This video was taken on 12.02.2018 @ 18:15. We were sitting in the house when we could hear it for a good 30 minutes. Finally we decided to go outside and record it. The video doesn't do justice to what it sounded like. It was a deep sound as if there was bombing going on at a distance. We did rule out fireworks by phone calls we made to surrounding towns.
I actually had this on my personal channel and had no idea of the popularity it quickly gained. I'd rather this be on my public channel so I've moved it here.
