Sasless,
You are right, for $10 I can buy a 47D -10, but not a 47F or the 60M. Nor can I get a NATOPS for the 53E, UH-1N, UH-1Y, AH-1W, AH-1Z. I wonder what they are trying to hide? Again, if it's no big deal perhaps someone (how about you Sas? ) would be willing to cut and paste the IGE/OGE perfromance pages for the 53E, 47F, and 60M as a show of good faith? I've searched the web and oddly enough no one has seen fit to copy and paste performance data for the above listed aircraft to any forum site. Maybe you know of some I don't? If not then just maybe our soldiers, sailors, airmen and Marines serving today don't see any a just reason to post -10 or NATOPS data on forum site which has as part of it's name 'rumor' so some unnamed guy who goes by Sasless can use the data as he sees fit? The reality is it's none of your nor my business.
