I have noticed on a few takeoff videos now that a rattling sound in the cabin occurs whilst in takeoff roll. Take a look at this video between 1:40 and 1:45: https://youtu.be/XdwN4LwwooM
In the video the rattling starts to occur at around 1min 40sec and ends at 1min 45sec. Out of curiosity, does anyone know where the source of this noise comes from and possibly explain it?
Thanks, Jacob 👍🏻
