I wasn't sure if this would hold water.
I was trying (badly) to use the S-V phenomenon to illustrate the point that the exhaust would dissipate 'sideways' and not just straight down as one might think.
Looking at the photo of the lem in flight the pads are well to the side and nowhere near in line with the exhaust bell yet they seem to have been protected.
My thought was that the pads were being 'swept' by the exhaust and therefor there never was any possibility of 'dust' getting anywhere near them.
Jus' a thought
