Keep in mind Heavens Above does not track all satellites - there are plenty more in orbit besides the Iridiums.
It's safe to assume that it was not a meteor if it lasted 40 seconds. Even 10 second meteors are very few and far between.
I've seen meteors which made my jaw drop, and there have been no "bangs". Occasionally, a super bright meteor enters the atmosphere and survives
for long enough to be heard - whitenesses often describe a sound like rolling thunder between 2-5 minutes after seeing the event. The vast majority

hanging in the sky in their wake for minutes after they themselves have gone - you'd know about it if you saw one of these! Events like this have a
good chance of making it to the ground, and leaving a meteorite, but they are considered "once in a lifetime" events (if you are lucky).
