I live near some flight paths so a lingering sound is normal but recently somewhere else a military style jet flew over head and the sound lasted much longer at a very high volume, long after we could see it anymore – why?

Because airplanes are very far away and very fast. Sound takes time to travel, and by the time the sound of the exhaust reaches you, the plane has moved much further away.
If you are trying to compare to a commercial jet, the military jet you saw was much more powerful (faster and louder) and likely flying much lower (closer to you). All of these effects combined produce a louder, longer-lasting sound.
