Was being followed by a Blackhawk that dropped off ads-b exchange over Wamego.
adsbexchange.com stopped receiving ads-b signals.
I heard the plane fly over really low. Got outside in time to see the blackhawk running balls out at about 1000ft AGL. Ran back in to look at adsbexchange and couldn't believe what I was seeing.
