I think that you fail to realize the differences between the services.
In the Navy, any officer/enlisted relationship that is 'unduly familiar' is deemed fraternization and is against the regs and a serious breech. Chain of command or not, same unit or not, etc.
shoot, in the Marine Corps, they have been known to go after people retroactively. As in, enlisted girl gets out of the military. Then, as a civilian, marries a marine officer. Said officer was then court martialed for violating the fraternization regulations. presumably the relationship started while she was still on active duty, the Marine Corps knew it and wasn't going to stand for that kind of crap (I'll get out then we're good).
I think that I wasn't the only Navy officer appalled at the whole deal surrounding that B-52 pilot a few years ago. The air force went after her for disobeying an order, but the Navy would have gone after her much earlier for dating enlisted personnel period. That isn't illegal in the air force, but is in the navy.
now, what all this has to do with the Blue Angels, who knows. I had heard a rumor that they liked married pilots, specifically to pre-empt shennanigans but that probably was just a rumor.
