Since I was incorrect in my analysis of what was being asked, now I understand what yall are talking about. No, there were no hinges, but I don't know those markings either, never had to install a loaded pod and I don't recall seeing them on a LAU-68. They are not hinges, I know that. Could be alignment markings, Bob, for the Jammer driver and load crew, MJ-1 lift truck, etc. Funny you remember the CDC's, cause they fell off my radar so dang long ago I had forgotten them, but I honestly think I still have some of those tech manuals for the F-15 from tech school. Wow, talk about flash backs.
