I'm going to chat about a subject that many websites and Blogs have covered endlessly over the last year or so and haven't come to any conclusions as to what it may be, Sonic booms. Apparently across the World and including the US, Canada and Russia and many other countries there have been strange booming sounds that no one can put their finger on.
So what is it ? Rumbling earthquake movements perhaps, seismic tremors or even the creation of some new Bore holes, yes, many have appeared pretty much overnight and taken a few houses with them. Maybe it is some unusual and never before seen UFO with an advanced technological force that powers it forth across the night skies.
Hmmn ! perhaps not, I do know several Bloggers who have pondered on what it may be, yet still don't know.
Consider that it might just be an Earthbound craft that is responsible for all the malady. So now that I have you thinking you want me to elucidate ? then I shall. Scramjet ! yep, you heard me right isn't it highly likely that the drone or rumbling sound that has affected many countries around the World is the testing of an craft that is slightly on the fringe of a break through of technology.
A high powered craft searing across the night sky at speeds in excess of Mach 5 would make one hell of a noise when breaking the sound barrier, maybe this is what all the noise is about.
Here is a link or two to stories relating to the testing program of the USairforce X-51A Hypersonic scramjet .
One last word, let's stick to the realties that are out there and leave the fantasy to You Tube fanatics and dreamers.
