Re: Not always.
Yes, Larry, I remember the STS41 D incident very well.
They had the RMS and used it to look at the ice and remove it.
I read other messages about the same issue. The place where the ice formed is not at all far from the left wing leading edge, forward section.
Maybe an explanation.
But wouldn't they have noticed the ice clump formation , even without the RMS?
