The pop occurs at 09.24 seconds, after which the recording device's automatic gain control (volume limiter) compensates for the noise (the waveform shrinks instantaneously, and gradually grows again for a half second or so). Something loud definitely occurred at around 09.24 seconds.
Here's a plot of a brief clip of a couple of seconds of the audio from the Corey Pelton video of the mishap as posted on YouTube. You can see the pop in the middle of the waveform plot at .83 seconds into this short excerpt and then reduced volume possibly from automatic gain control as you say.
The audio of this short excerpt is attached as a .zip file which will open on most computers but not most tablets or phones.
