Locking the harness is in the step 1

Yes, because of tragic lesson learnt.

Megan: Taking your approach a step further, by looking at timing for each 90 degrees change of yaw from the start of the yawing, it is increasing at an angular acceleration of about 9.5 degrees per second squared until impact with the water. So by the 10 second point into the video in #8, horizontal acceleration experienced by pilots is ~0.2g while by 15 second point (while helicopter is still in a relatively flat spin but starting to descend), horizontal acceleration is already ~1.0g. Even that would already have made it hard to control the helicopter quite aside from the jammed pedals.

Unfortunately that's not really an option when involved in a vertical reference operation like this
