Even with NVIS these days my mantra regarding supplemental aircraft light is find a reason to turn it OFF, rather than ON. Get plenty of white light out there to illuminate wires, improve general vision and assist if you have an NVIS failure. I turn it off rarely, usually only due to particles such as moisture, smoke or dust in the air.
Yup, 20 years ago I was teaching people to use a mixture of white light and NVIS - there had previously been the mantra that the two should be mutually exclusive but the improvements in goggle technology had not been fully appreciated.
Judicious use of the steerable landing light and often a white spotlight from the cabin helped spot those sneaky little wires that are often hidden in trees.
Lights not a factor in this case though, they had plenty of daylight left.
From the updated news report it seems one crew member survived so maybe answers will be forthcoming from her.
I note the pilot's age was 63, presumably single pilot commercial ops over the age of 60 is allowed in the USA?
