I had 2 flyover about 25min apart at 5:30am last night, heading the same direction as OP described and also flying lower than I've seen them and didn't appear on ADS-B. I've also never seen a C-130 flying through here before, wonder what they were up to?
From the description it sounds like a C130 flying nap of the earth.
