Not wanting to wait through the prologue, I skipped ahead in the video, where I searched in vain for the real-time drop. It's bizarre that they apparently didn't show it even once, especially since it can't have taken more than a few seconds (the chamber's height is 37.2 meters [1], so t_max = √(2h/g) = √(2×37.2/9.8) = 2.75 s).
