Crab,
Please show some respect for your Elders here!
But....exactly as you say....I just hit 70....and consider myself an Old Fart.
I always had excellent vision except for a Red/Green issue that caused a problem on two occasions during Medicals well after becoming an experienced pilot.
I thought about the Bright Light to DARKNESS in a Jet Ranger thing last night while sitting on my Porch looking across the bay to the lights on the other side.
I considered what it might look like peering out of the Wind Screen of that Jet Ranger if there were no lights on the other shore.
The Pilot was 75....well experienced....but his eyes had some normal wear and tear on them from all those years I am sure.
The average Jet Ranger is not an aircraft I would like to fly instruments in....especially in the middle of the night after a very long day.
How well it was equipped should be examined by the investigators among other issues.
The Human Factors issue in this tragedy surely needs examining closely.
