DS & I were discussing his SLS experiences and he was explaining the briefing where they covered LOA's. We understand they are rare, what they are for, how they are used, etc. Where we get confused is around nominations associated with LOA's. We've read as many back posts on LOA's, it sounds like in some cases a nomination is provided *if* the candidate is not a principle nom or did not make the ten nom list. (Presumably provided from other nomination sources) In other posts, it sounds like the congressional committees work to get LOA holder's higher in the queue as they are high probability. So they are more likely to get a nom. And in others, there is reference to LOA's being contingent upon obtaining a nomination, which makes it sound like you have to run the full nomination process and be selected. Is this variance between the academies? Or are there different types of LOA's? We recognize it's somewhat irrelevant right now because of the odds. We are just trying to understand how it works. Any clarification would be welcome! Please use short sentences as clearly we are missing something simple! Thanks!
