Why Does US Navy Still Perform Burials at Sea?

I had to cry watching this , my dad and my uncle were both on aircraft carriers in WW 2 . My uncle was shot down in an Avenger , never found or brought home to this day . My dad survived , but never talked about his experiences , much too painful I'm sure . It took me a long time to realize that my father never taught me hate for the "others " who killed his brother . I grew up without prejudice or hate . Thanks dad RIP ...
