Impact should have occurred at approximately 71seconds, at which point the simulation indicates it was descending at 43 mph and moving east at 32 mph, for a total speed of around 54 mph.

Very impressive analysis!
I do have a question regarding the above. Is the terminal velocity of an unpowered Mavic Pro only 43 mph? Thanks!

Altitude dependent but yes - that's correct.

Thanks! (I don't live in Denver so sea level numbers are valid for me?)

I've seen some pilots do what this guy has done before and normally they CSC it to let it freefall to preserve battery before re-arming the motors in time for a regular landing. I believe they freefall at -18m/s or so. Certain drone parameters would have needed to be altered so you could re-arming the motors at 5% battery as it normally won't let you restart if battery is <10%.
And if you're wondering, no I've never attempted this before.
