You can clearly see the 2 explosions before you can hear them.
I personally didn't know about this. Generally in the middle of the battle you don't pay attention to details, and even if you wanted you might not hear much because there are explosions and gun fights all the time.
If you listen carefully you can also listen birds on 00:02 and 00:11, another thing that had escaped me until today.
I know I know, seagulls don't travel faster than sound waves, nor do swallows carry coconuts!
