A big bang sparked rumours of a sonic boom among Leybourne residents last night.
Dozens of people took to social media to report the loud explosion shortly after 10pm.
No-one knows what was behind the noise, but some rumoured RAF jets could have caused the blast.
A resident posted on the Leybourne Village Facebook Group. He said: "Could it have been a sonic boom? We do get them occasionally when the RAF scramble overhead."
In 2014 a loud noise heard across west Kent turned out to be a sonic boom created when an RAF Typhoon intercepted a Latvian plane.
Meanwhile, Jamie Stewart joked that angry reactions to the introduction of car parking charges in nearby West Malling were behind the noise.
