&gt;... at Area 51 (their airfield for testing experimental aircraft)<p>I&#x27;m Canadian but that reminded of some relatives who sent a video of a birthday party. They were outside and a big booming noise could be heard and they all looked to see what it was.<p>I didn&#x27;t think much of it since it was hard to hear other than a sort of jet sound but they lived there and seemed to think it was different or unusual in some way.<p>They lived in Apple Valley in the &quot;high desert&quot; (I didn&#x27;t know what that meant) years later I found out Area 51 is pretty close.<p>I don&#x27;t beleive in aliens but it was interesting to know  the video had a mysterious aircraft and Area 51 in it.
