What caused the mysterious 'loud bangs' heard in some areas of the UK?

[Altaira]

There were some strange bangs heard across some parts of the UK. One of my friends told me she heard some repetitive bangs like fireworks or tunder but there are only speculations of what this could be.

Has anyone heard about it? I've been very bussy recently so didnt have much time to research this but I think this could be a chem bombs. Chembombs a re the newst technology used by the geoengeneers to alter the athmosphere. This creates thick screen on the sky without leavving any chemtrails.

Here is a little bit about the so called stange noises.
A series of mysterious, apparently inexplicable explosions heard around the UK were eerily reminiscent of a futuristic 'pulse detonation jet' an expert has said.The strange bangs were reported around the UK (and as far away as New York) on 29 November, with residents from Aberdeen to Croydon noting the blasts on Twitter.Dr Bhupendra Khandelwal*told the Mail*that the sound -- which can be heard below -- sound like the type of engine on which he is working at the*University of Sheffield. ...........

this sounds to be the cause: Pulse detonation engine technology.
if so, could this tech be sanctioned for wide usage?

here's another article.

So secret, its existence is not even acknowledged: Futuristic ‘Aurora’ spy plane that travels at SIX TIMES the speed of sound is blamed for mysterious booms heard at the weekend



The origin of the mysterious bangs heard across the UK and New York at the weekend are yet to be officially identified.

But a leading theory is that they were created by an aircraft possibly travelling at supersonic or hypersonic speeds above the Atlantic.

This has led conspiracy theorists to attribute the booms to a spy plane rumoured to be under development by the US military, under the codename Aurora.

Within minutes, Twitter users had started spreading hashtags – from the straightforward #loudbangs to the somewhat melodramatic #omgwereallgoingtodie.

At around the same time, residents in locations including Buffalo, Cheektowaga, Clarence and as far north as Niagara Falls on the east coast of the US also took to social media to report the unusual noises.

This sounds plausible but this is the main job of the MSM, to create believable lies.
