They were concerned about it, but then they realized the shuttle would fly so little as to have negligible effect. Look around the AW&ST archives and you'll find it. the principal problem is the SRB use an ammonium perchlorate in the fuel and that released at upper atmosphere, causes problems... I believe the sovs use H202 and Lox/kerosene. henr would know better...[ -- ============================================================================= Pat @ grebyn.com | If the human mind was simple enough to understand, 301-948-8142 | We'd be too simple to understand it. -Emerson Pugh =============================================================================
