I think it would be helpful to have a subcategory of Thermal protection systems of which AVCOAT 5026-39 would be at least one member. PICA/PICA-X would ostensibly be another. I'm not sure of the process for getting new categories approved so will just leave the idea here and see what others think. N2e (talk) 14:04, 26 December 2010 (UTC)[reply]
