Demented. Judging by your comment, working with external loads is not your area of expertise.
This is one of many examples of how external work is done on a daily basis.

This is the type of work I have been directly involved with in North America and here in Europe, (+25 years).
No discussion, this job was executed and completed without incident.
However......lets have a good look 7th picture see what could/should have done differently.
1.) Lead flight helper, (red overalls) no helmet, no radio. In direct down wash from MR. Standing directly in flight path of the load. No escape route.
2.) The 2 flight helpers, (riggers?) no hi visibility clothing (black & white/gray) blends in great with the painted(?) black/white deck. No radios.
3.) No mirror(s) on the A/C. Pilots door not removed for better visibility of the landing zone.
4.) The 2 flight helpers, (riggers?) lots of ropes attached to their belts to get tangled up in.
5.) Missing at least 2 ropes on the transport platform. Makes it easier to control and position the load on arrival.
6.) Optional: 4 Riggers might have been a better option if they had the trained personal.
7.) Optional: Pilots choice: 5-10 meters longer line. Less down wash.
Using hand signals to communicate with a pilot looking through his feet out the chin bubble in this day and age is foolish and dangerous.
Clear radio communication between the pilot and all ground crew is priority one during slinging operations.
It's clear this was a "big show" judging by the number camera's, helicopters, people near the heli-deck during deliver. The number of "vip's" in the video after the car was delivered looked impressive too.
Money did not appear to be a problem with this project. Money talks and big money talks even louder. So keep the job safe with good planning, risk assessment, and good teamwork.
Last but not least, make sure the crew, (airborne and ground) have the tools and training to complete the job safely.
