Strange Sounds in the Sky: What Are They?

Out of the vast sky come sounds of trumpets, of metal grinding against metal, booming noise, buzzing, humming....

For over a decade there have been reports worldwide of 'strange trumpet like sounds' in the skies.  The explanations are varied and seem to have a 'toss it at the wall and see what sticks' line of thought.

The explanations offered include:

Apocalyptic horns - Religiously inclined tend to hear these are some sign of the end times, yet Biblically, there is little support for any warning trumpets of the random nature reported. What is in the Bible is from the Book of Revelation, where seven trumpets are sounded, one at a time, to cue apocalyptic events seen by John of Patmos in his vision1. The seven trumpets are sounded by seven angels and the events that follow are described in detail from Revelation Chapters 8 to 111. The trumpet sounds are meant to punctuate the Great Tribulation period with ever more disastrous effects2. Most of these trumpets and their effects have already been discussed in the section on World War III, because they reflect the worldwide consequences of a massive global war fought between the main military powers at the end2.

Sonic Booms. These are LOUD but also very, very short in duration. Duration of sonic boom is brief; less than a second -- 100 milliseconds (.100 seconds) for most fighter-sized aircraft and 500 milliseconds for the space shuttle or Concorde jetliner. (Wikipedia)

Aircraft - In the 1950-1970's populations near major flight bases or test sites were often subjected to regular sonic booms. Some instances, the government even conducted tests to see what impact they had on the population. Since then, however, the Federal Aviation Administration (FAA) has created guidelines to minimize the impact of sonic booms on the ground 1. According to the 49 U.S. Code § 44715, the FAA is responsible for controlling aircraft noise and sonic boom to relieve and protect the public health and welfare 2. The FAA prescribes standards to measure aircraft noise and sonic boom and regulations to control and abate aircraft noise and sonic boom 2. Sonic booms are not categorically illegal in the United States, but they are subject to certain regulations 1. Compliance with regulations is crucial to ensure the safety and well-being of communities.  Since not all the reported sounds have been over the USA, it is possible some are being caused by living in a country where there is laxity in protecting the communities from regular flyovers with attendant booms.

Sky quakes - Heard widely these are largely mysterious but are believed to be caused by any number of things, including air pressures , earthquakes, and weather fronts. A skyquake is a phenomenon where a loud banging sound is reported to originate from the sky. The sound may cause noticeable vibration in the ceiling or across a particular room. Those who experience skyquakes typically do not have a clear explanation for what caused them and they are perceived as mysterious. See Skyquake - Wikipedia

A careful hearing of the videos suffer from similar problems and cannot be taken seriously because of those issues.

Problems: Most videos or audio are suspect. They offer no real evidence that is supported by news articles, police reports, or similar evidence. It is too easy, and has been for several decades, for such things to be hoaxed. Playing with special effects and new video recorders can lead to some interesting results. They are often produced with heavy, sensationalized graphics, titles, wild theories, and bad music.

What would help support such a video?

• Captures of people unrelated to the one taking the video reacting to the sounds. even film in cities has been too void of traffic and people. Surely, if the noises were that loud and that long lasting....people would be out on the streets.
• A newspaper or broadcast - something - that would verify place and date and time.
