   Eerie. I thought CH have compound material blades. Or is it EH?

   The CH blades are composite material. The newest ones have titanium on the leading edges to help them wear slower. I suppose that might create the halo, but it seems to be mostly a trick of the Afghanistan dust reflecting the ground lights. I don’t know what EH refers to.

   Composite, yes. My memory is going steadily.
   But re the effect – it has to do with static charge accumulation on the blades and on the dust particles, as a result.

   My powers of observation aren’t any better. If the halo was reflecting the ground lights, it would be more green than it is.
