Some good ideas but the link terms were often too specific (e.g. vehicles should work as a link). Also there are at least three equally valid solutions to the grid using your link terms. Oscar and Romeo are both literary characters who died, so either one could swap with Juliet as that also represents a letter in the phonetic alphabet. It has potential to be a a really, really good grid, with some editing, but as it is, it just doesn't work, as it's only solvable by pure luck or mind-reading
