Maybe this thread should be renamed the Alicia/Michael debate. In all seriousness, Boxhall's navigation was NOT incompetent. I believe he did the best he could under the situation and with the data available to him. And it is entirely possible that he did make an error in using the tables, but that should not invoke a label of incompetence. At best, the position was going to be an estimate only. Once rescue ships can make it to the general location, they would still need to get visual confirmation. That's why you have rockets and flares to help. Unfortunately, even if within range of seeing these, it does not necessarily trigger others into taking appropriate actions. But that is a topic for another thread.
