In 2017, a whole series of mysterious and very loud booming sounds swept around the world (mainly in different parts of the United States), like echoes of a big bang. At the moment there are already 64 of them. In the English-speaking press this sound is called simply "Boom". The mystery is that the cause of these booms has not been established, although in one of the last cases, in Alabama, a loud boom even hit the recording equipment.
A mysterious loud boom in Alabama was recorded on the afternoon of November 14, 2017. Many people heard it and immediately rushed to write about it on social networks and ask each other what it was. They asked local officials, the military, even NASA and did not understand whether they should look for a bunker or pray? People put hashtags #WhatWasThat #LoudBoom (#WhatWasThat #LoudBoom) and left comments and their versions of what happened.
The sound was so loud that it was heard in several areas at once, including residents of the cities of Birmingham, Arab, Oxford, Anniston, Hayden, Kimberly, Center Point, Jasper and Gardenale.
Soon, the first statements from government organizations came out. The National Weather Service announced that they did not see any fires or heavy smoke anywhere on their satellites, and that there was nothing on the USGS instruments indicating an earthquake. They speculated that the loud boom could have been a sonic boom from an airplane or from a meteorite falling from a current Leonid stream.
Soon, the US Geological Survey made its own statement and they said that the seismic instruments in Centerville, Alabama, recorded a big boom on November 14 at 2:39 pm EST local time.
The University of Western Ontario then stated that their instruments detected a massive infrasound signal at 3:02 pm that lasted for about 10 minutes.
Later, a representative of NASA made a report that most likely it was some kind of fireball, although there could be a sonic boom from an aircraft or even a large explosion that happened somewhere on the ground. That is, NASA also only made an assumption about the nature of the boom, but knew nothing (or hid) that it was actually.

It is doubtful that it could have been a meteorite from the Leonids stream, these stones are too small to make such a noise. Also of interest are reports from several people who saw a large contrail in the sky.
According to Popular Mechanics magazine, mysterious sound "explosions" are most often heard from the flights of military supersonic aircraft. However, none of the US Air Force acknowledged that tests were being carried out in Alabama at this time.
One of the local residents about the sound she heard said that she almost got a heart attack because of it, it was so loud.
“At first I thought there was a shotgun or a firecracker nearby, but it was too loud for that. It was as if a tank had crashed down from the sky next to me. My husband says that it must have been a mini-meteorite from the Leonids, but this is nonsense."
Astronomer Ron Hranak confirmed in an interview with CBS that the Alabama boom was definitely not caused by Leonid meteorites, as they are too small for such an effect. Most of them do not even reach the ground, but are burned up in the atmosphere.
So what could be causing these sonic explosions? Secret military flight tests? Testing ground controlled explosions? Some are of the opinion that the whole thing is in as yet unexplored weather phenomena and booms may be the result of strong electrical shocks in the atmosphere. Or maybe these explosions are the result of UFO flights? The truth is somewhere nearby, as a well-known character used to say.
