2020-04-09 - Waterloo, IA - Light

While looking towards North sky spotted small starlike light moving from west to east threw big dipper handle constillation. First light appeared moving very fast high in atmosphere, then came another light moving in same direction about 6-7 seconds behind staggered a little to the south. Then more appeared staggered '.'.' In this type of formation about 5-8 seconds apart. Turned on flightradar24 app and saw lower flying aircraft on radar but not the lights flying above them. These were not space x satellites. The last 5 lights flying west to east dissappeared into the night sky as if flying out towards outer space and just dissappeared. Objects made no noise. Could hear lower flying aircraft that were appearing on flightradar24 app.
