FIRST ON 3: Another “boom” felt downtown and in Leland

WILMINGTON, NC (WWAY) — Folks downtown and across the river in Leland heard another mysterious “boom” this afternoon around 3:30 p.m.

One of our viewers emailed us from Leland to say her dishes shook for a second.

Here at the station it felt and sounded like either someone had hit the building with a vehicle or like someone dropped something huge on the roof.

No one knows for sure what causes the booms. Many believe it’s a sonic boom created by a military jet from a nearby base. Others say it’s something called the “Seneca Guns,” a phenomenon caused by shifting plates out in the ocean.
