Given this was single pilot, I wonder how often such 'high-end' operations are performed with 2 pilots? Or at least have the the pilot supported by a 'spotter' It must be a handful flying a complex a/c like this in such a messy environment and easy to loose awareness of hazards. I know that SAR operations that have to routinely get in and out of tight spots have multiple spotters with precisely defined roles. I doubt the wealthy customers would balk at the extra cost.
