Remember, the sound isn’t really coming from the tip of the bolt. The majority of it is coming from the super-heated air around the bolt along the whole path.

Yes, so the sound should last a while as bits of it from far up the bolt reach you, but I don't understand why the start of the sound would be delayed.

Human memory isn't perfect, to be fair.
The start was likely quiet enough to not be audible through the airplane walls.
The start of the sound is basically instantaneous.
