Yesterday on Hiatory Channel I watched a show talking about area 51. I believe it was a mystery quest. They had a part that talked about "Skyquakes". Apparently peoples' houses will shake, things fall from the walls, ground feels like its shaking, etc. Most believed this to be earthquakes but seismographs picked up no activity in the area and it was actually the sky that was shaking. It is unknown what causes skyquakes, but one theory is that an experimental hypersonic plane moving in excess of 4,000mph causes the sky to shake. I'm not sure whether this is correct or not but it seems logical if area 51 really is a site for reverse engineering extraterrestrial technology.

Is this also the phenomenon that I have experienced where I live in the UK ?
