Steve76....the logic of your statement has a wee tiny flaw....Two engines vice one is irrelevant until one of the two engines gives up the ghost....at that point....it does most certainly become an issue.
I would gladly fly a four engine helicopter that could hover on one engine anyday....as compared to the current situation of flying aircraft that will not hover with zero engines. Logically, not a very useful argument....but gets my point across that full single engine hover capability at all phases of flight sure beats the current one we deal with.
That being said....this has nothing to do with the event under discussion in all liklihood. It will interesting to hear how this plays out.
Anyone who flew in "A Land Far Way" and had some well intentioned ground pounder toss a Trip Flare onto the landing spot in the middle of the night (before NVG's), can appreciate the loss of night vision....heck...almost all vision when very near to the ground and surrounded by hard bits all around. It can get very hairy for a bit.
