Unknown over Perryville, MO

The report, as filed

I live about 90 miles south of the St Louis airport. It's normally very quiet here. On Jan 11 and 12, I heard and felt massive rumbling. I've lived on air force bases and this sounded like we were living at the end of the runway. On Jan 11, at about 4 pm, I was outside, when this loud jet sound (like a C5) began. It was slightly overcast and I could not see it or really determine what direction it was coming from. I actually expected a massive plane to come through the clouds and crash. I felt the rumbling and the roar was as loud as being at the end of the runway when B-52's or C-5's are taking off. It sounded very close. While I often hear and see aircraft flying, they are very high in the sky and cannot be heard inside my home. This lasted 7 min or so and then just suddenly stopped. I dismissed it as some kind of military exercise even though i don't live near a military base. On Jan 12, at about 10:30 am it happened again. This time I was inside my home and it felt like it had to be directly over the house. I went outside but once again, it was slightly overcast and I couldn't see anything. This lasted about 10 min and stopped suddenly. A few days later, I asked my husband if he had heard of any military presence in the area. I told him what happened, and he said it could have been aircraft testing of some sort, but that he was not aware of any exercises. Today, I was browsing UFO reports for an entirely different reason and noted two reports on Jan. 11 describing the same sounds I heard on the 11th and 12th. It never occurred to me that this noise was unidentified...
