Whip cracking sounds have sometimes been reported from the turbulent wake following landing planes. I've heard some very weird sounds from the wake, but this is the one and only time I've actually experienced the whip crack, which is at 0:45 in the video. The recording doesn't really do it justice - I nearly jumped out of my boots it was so loud and sudden!
If you look carefully before the whip crack you can see a visible effect of the wake as a horizontal line passing downwards through the horizon at 0:39 and visible for over 3 seconds. Also you can see the camera shake after the crack as the wash hits it (the movement at 0:51 is me panning slightly).
For geeksters the video finishes with a repeated recording of the whip crack and a display of the sound spectrum of the entire recording.
The plane is a Turkish Airlines Boeing 737-800 landing runway 33 at Birmingham Airport (BHX). The conditions were: wind calm, temperature +5C, dew point +3C, barometric pressure (QNH) 990hPa
