Wow, very tragic story DD. Sad that it could have been so easily avoided.
To your question, guessing the attachment/recovery point on the stuck vehicle probably will be the weakest link by the time I put my package together.
Digging into the subject, my conclusion is recoveries are just dangerous no matter what is used and any of the equipment can fail. The heavier the vehicle, the more the dangers increase. It appears dangers can be reduced, but never eliminated.
Even chains can snap and recoil too. See this video beginning at 3:58. 10’ of chain go through the rear window.
