On Oct. 25 around 3:30 p.m., a sound caused a stir with a audible boom and shake.
Residents quickly turned to social media to find out if others had heard the boom. Facebook posts were reported from Salisbury, Seaford, Delmar, Dagsboro, Ocean Pines, Hurlock, Princess Anne, Bishopville, Snow Hill, Vienna and Fruitland.
Patrick Gordon, NAS Patuxent River public affairs officer, said while they do have aircraft flying in the area, none were approved to go supersonic, so they were not the cause.
Keith Koehler, NASA Wallops spokesperson, said he heard nothing in Virginia.

The low-frequency noises - which sound a little like moaning when sped up - could help researchers track the ice shelves as they collapse.
The singing tones come out of the surface of the massive Ross Ice Shelf when the winds blowing across the snow dunes cause it to vibrate. That means they produce the "tones" almost constantly, and now scientists have found they can listen to them.
Doing so could help them spot how the ice shelf is forming from afar, and track the damage that is being done by climate change by tuning into the tones.
Ice shelf collapses can be drastic and sudden. When they do, they can change the flow of water and raise sea levels, making it important to watch for any signs as they occur.
To try and understand how the Ross Ice Shelf is arranged, scientists put 34 very sensitive seismic detectors under its surface. They then monitored its vibrations from late 2014 to early 2017.
When they checked in on that data, they found that the snowy coat that sits on top of the ice shelf appeared to be almost constantly vibrating.
It was then they found that the shaking was caused by the winds travelling across the huge snow dunes and making the snow rumble, like a huge drum.

The two minute and 21 second video was reshared by another YouTube channel today.
Comment: The footage was originally published in January, 2018.
It is the latest in a string of unusual noises to heard from the sky worldwide - with unusual hums and horrific "trumpet" noises.
Scientists have been theorising what is causing this noise, with theories ranging from shifting ice to distant storms.
Krupinski shared the video of him standing in a snowy landscape, which is silent apart from a constant low buzz - and a passing snowmobile.

Police were called to the area of Washington Street and Campbell Road Avenue just after 10:30 p.m. after dozens of residents reported what sounded like an explosion.
People living within blocks of the area of the explosion report their homes shook and some even say pictures fell off of their walls.
