Lu,
Anyone who takes your word gets just hot air.
Helicopters do not glow in the dark, you cannot see them coming miles away, you are mistaken, you are wrong. Don't try to bend the words of some poor unsuspecting fellow who makes static equipment, don't ask the uncle of a cousin of a friend of an instructor to do an "experiment" for you.
I had email from several military high time pilots who all wonder what planet you are from. All agree, with hundreds of hours of night and night goggle time, that helos do not glow in the dark. But you stand on the ramp in Iran 25 years ago and see it. Get your eyes checked.
