As you just said...you understand that it could be dangerous because it is the Military.
But, yes, people do refer to the Airforce and being the safest because, Airmen tend to have lower standards to enforce than other branches.
This is kind of an age old thing. Other branches always thought Air Force as kind of pansies.
We are the youngest service........we are only 59 years old and derived from the Army
Our basic training used to be shorter. (I believe its about as long as Navy Boot Camp now)
We only handle our weapons every 2.5 years for training.
Our physical fitness standards are a bit more laxed than others.
Our base facilities tend to be of better quality. Though I found that a little hard to believe. I've been to Army Posts and Naval Stations.
We are not taught hand-to-hand combat
Nor do we have an infantry.
I remember in your last question you wanted to make sure you had time to spend with your wife.
In the Navy, you are out to sea quite a bit. Yes, you do get shore duty from time to time, which is about 3 yrs. But, you can be out to sea for as long as 9 months.
But, then again in the AF you can wind up getting stationed somewhere in which you will not be able to bring your wife for a Year.
So, really its up to you.
My Brother is in the Navy (11 yrs.) and he loves it. He has a wife and 3 kids.
I was in the AF and I loved it. But, I was also single. I didn't have to worry about anyone but myself.
