Well before the age of HIPPA. Many military bases have limited number of nurses and use Medical Technicians.

People that live in dorms have a tendency to drink and talk.

How many people saw her before the doctor did?

Many US Air Force bases are really just small towns. Word gets around pretty fast.

When a high-level Officer retires there is usually a big to do. Change of Command Ceremony, a party, usually with cake, etc. This takes some time to get together and hopefully his replacement will have enough time to get there.
Usually, the notice of retirement takes place six months to a year in advance.

It was a real surprise when a Colonel, the Base Commander, walked into the retirement office early one Monday morning and told the people he was going to retire, and they asked when.
He told them, "If at all possible, today, make it happen."

Everyone in the office was stunned and the Personnel Commander took him in to an office to talk to him. When they came out the Personnel Commander told the people to get to work on it. I guess they pulled it off.

Later it came out that the Base Commander had to take his 16 year old daughter to the base Emergency Room because she had a Coca Cola bottle in her pussy and couldn't get it out.

The Commander knew word would get around so, he retired.

Former Vice President Rockefeller died while banging his mistress.

So funny. I worked at a ski resort in Colorado USA and we had a bunch of young adults from Australia come to work the winter.

At the time there were two regular commercials on USA tv.
One was for Fosters

The second was for Subaru Outback. It was set in some outback village and was a bit silly. Had a crock in a mudhole in the middle of the street. Kangaroos hopping down the street. These Crockadile Dundee type guys walking around.

One of the people working for me said she had never heard of Fosters and wondered if we Yanks thought that was what the streets of Australia were really like.
