UFO Sighting in Joplin, Missouri on July 4th 2015 – SE to NW overflight of objects-probably military 1 unknown fast blimp gray no lights

July 4th evening. Starting 8PM ish SouthEast to NorthWest of what first appeared to be helicopters. 2 to 5 at a time these lights were in the sky from 8PM to 12PM and beyond. Out of ordinary no# of flights in odd direction but strange was silence. In fireworks lull was obvious craft were totally silent. Visually obvious helicopters but silence was odd. What cinched the WTF category was dark square object flying same path, keeping pace, no exterior lights. Looked like city blocked lifted up to 50degrees flying 150-200mph. No film no pictures. What's the point. Photographic evidence has been irrelevant. People will or won't believe. BS perspective: odd govt overflight of Joplin July 4th. Many 20-50 helicopter like objects flying SE to NW from 8PM to 12PM. Estimate 20 - 50 craft. Totally silent. 1 odd city block size object same flight path silence also. No agenda No baloney Just sayin...!!!!
