Was watching the news when I overheard a loud helicopter thundering over my house, I got up and ran to my south window where I saw a black military attack helicopter hauling ass just over my house at or below 300 feet from my roof top.It was going east to west then immediately turned south towards a thin dark grey disk object that had a white light modulating from it.The disk appeared less than a mile away heading north when it was as if the helicopter spooked it and it simply made an abrupt left turn heading northwest at an amazing speed towards Kansas City, Missouri.With the black military attack helicopter turning very hard "almost vertical" around heading northwest in pursuit of it.What ever the object was, it definitely had the ability to out run the military helicopter and disappeared from sight.
