How about a little help? The planefags got me interested in watching the air traffic myself. The free ADSBexchange shows the military planes but doesn't seem to have a replay/playback function. Flightradar24 has a playback function but doesn't show the military helicopters that have flown past my house. I've noticed some of the police helicopters are also not shown.

So my question is this: Is there a resource that shows all or most of the military aircraft that has a replay/playback function?
