It's been a while since I’ve watched Generations... I never put much thought to it, but what do you imagine Starfleet did with the remains of the 1701-D on Veridian III? Sunken ships in today’s terms are left as a memorial; and in those cases the loss of life is usually staggering. Did anyone even lose their life in the crash? I can't imagine they would have left state of the art technology just sitting around for anyone to come take a look at. Do you think they stripped out any reusable technology? Did they had the entire ship scraped, sent to some kind of junk yard for recycling? Or was she left intact as a homage?
