There is a famous scene in Star Trek 2 - The Wrath of Khan, where after heroically saving the Enterprise, Spock is "buried" with honours.
While Spock's death is possible the only one of a main character, (although I could be wrong on that as I've not watched all Star Trek series) it definitely is not the only one in Star Trek history, in fact there have been so many death's of Security Officers that it has become it's own trope.
However I don't recall any other such services being held for the valiant Security guys at any other of the Star Trek series or films.
Are there any other examples of such full honour burials in Star Trek?
