Nah, divings and surfacings become routine and humdrum. They probably knew the cameras were rolling and got concerned looks on their faces for dramatic effect. :-)
Sure, Fast Attacks like the San Francisco get to dive and surface on a regular basis, but the Boomers that I rode (pre-Ohio) only averaged one dive and one surface per patrol.
OK, sea trials were different, and we got to do real submarine things then, but that first dive was always significant. It had been three and a half months since we'd been underwater, and there would have been a lot of turnover during the off-crew period.
