Wow, haven't seen "Watch In The Sea" since O School Key West in 1962. I'm pretty sure it parts of it was filmed in Hatteras and I'm certain that Charlie Hibbetts (SOG2 at the time) reading the gram. I'm also certain that wearing whites in the display room was a very rare event.
Here are a couple of more old films for you. Quite the "stroll down memory lane".

I'll add one more for your watching enjoyment. It shows what actually happens when a sonobuoy hits the water. It appears to be made up of several clips based on the time indicator.
